Presidential historian Jon Meacham says former President Richard Nixon's Watergate scandal looks a bit like what's happening today.

Meacham, who has written biographies on Thomas Jefferson and eulogized former President George H. W. Bush earlier this month, brought some historical context to MSNBC's Morning Joe Tuesday morning. He described how Nixon's downfall coincided with an ongoing investigation and falling markets — much like what President Trump is seeing right now.

In the two-year fallout after 1972's Watergate break-in, Nixon started out claiming he was "not a crook" — something that "would've fit on Twitter," Meacham noted. From there, the economy began "souring," Meacham said, suggesting the markets could be a "barometer of what's going to happen to President Trump."

Then, Meacham brought the conversation into the present day by discussing Russian efforts to influence the 2016 election in favor of Trump. "If in fact Donald Trump knew about" these efforts, that raises the "live question" of whether these actions fit "the definition of treason in the Constitution," Meacham explained. It all makes for an "existential Constitutional crisis" in which a president could be an "agent of a foreign power," Meacham added.

Los Angeles Dodgers third baseman Justin Turner celebrated the team's World Series win on Tuesday alongside his fellow players — even though he tested positive for COVID-19.

Turner was pulled from Tuesday's game against the Tampa Bay Rays after he tested positive for the coronavirus, but he still returned to the field after the Dodgers won, "holding the trophy, kissing his wife and mingling with other players, coaches, team officials and family members," The New York Times reports. He was also seen taking off his mask during a team photo.

The Dodgers learned that Turner tested positive partway through the game, and the team "immediately removed" him and "instructed him to isolate," The Wall Street Journal reports. Still, Turner "defied orders" by returning to the field to celebrate, and "when told by MLB security that he had to leave," Turner "refused," the Journal also reports. In a tweet, Turner said he feels "great" and has "no symptoms at all."

Turner's return to the field despite his positive coronavirus test immediately drew criticism, with USA Today's Gabe Lacques writing that it was a "galling image." Speaking to reporters after the game, Dodgers president of baseball operations Andrew Friedman said that "I don't think there was anyone that was going to stop him from going out" but admitted that "if there are people around him without masks, that's not good optics at all."

A Washington Post/ABC News poll of Wisconsin and Michigan released Wednesday morning had good news for Democratic presidential nominee Joe Biden. In Michigan, the poll found him beating President Trump by a modest 7 percentage points among likely voters, 51 percent to 44 percent, within the margin of error. But Biden's lead in Wisconsin was 17 points among both likely and registered voters, a lead so large The Washington Post suggested it might be "significantly more bullish for Biden than some other public polls" because of "variation in random sample surveys."

Biden's Wisconsin lead in the RealClearPolitics average is 5.5 points (49.8 percent to 44.3 percent), and FiveThirtyEight puts Biden ahead by 7.1 points, 51.4 percent to 44.3 percent. RealClearPolitics also gives Biden a 9-point lead in Michigan (50.5 percent to 41.5 percent), while FiveThirtyEight pegs it at 8.3 points, 50.9 percent to 42.6 percent. Biden has led in both states for months now; Trump won both by narrow margins in 2016 — 10,704 votes out of 4.8 million cast in Michigan and 22,748 out of 3 million votes in Wisconsin.

Trump's approval rating and poll numbers are down in both states compared with the last Washington Post/ABC News poll, and the pollsters attribute his especially precipitous fall in Wisconsin — Biden led by just 6 points in mid-September — to the COVID-19 pandemic. Wisconsin is "now reported to be third in the nation in per capita COVID-19 cases, with a 53 percent increase in average daily cases in the past two weeks, a record number of hospitalizations, and a 112 percent jump in deaths," ABC News reports. And the polls bear that out: Biden now leads Trump by 20 points on who Wisconsin voters trust to handle the outbreak, from 7 points in September.

Biden's lead is also fueled in both states by double-digit leads among women and majorities of older voters.

The polls were conducted via phone, mostly cellphones, Oct. 20-25 among 789 likely voters in Michigan and 809 likely Wisconsin voters. The margin of sampling error in both states is ± 4 percentage points. Peter Weber

Trevor Noah had a good laugh on Tuesday's Daily Show about a Florida man who stole a bulldozer from an Arby's and tore up Joe Biden lawn signs in people's yards, followed by a good-natured lecture on how politics has taken over our lives. "Meanwhile, President Trump, the Florida Man in chief, is holding coronavirus giveaways all across the Midwest — and he clearly is getting tired of attacking Joe Biden because now he's putting effort into getting Kamala Harris," he said. Trump's attacks on the Democratic vice presidential nominee are outlandish, mendacious, and a little revealing.

"I love that a 'female socialist' president is Trump's worst nightmare," Noah said. "Because now I can just picture him waking up in a cold sweat and Melania just being like, 'Oh no, honey, was it the female socialist president again?' I'm just kidding, Melania and Trump don't share a bedroom." He also found it amusing that Trump is criticizing Harris' laugh, or anything else about her. "My man, you look like you were built by the same company who made the Tower of Pisa," Noah said. "I'm surprised people don't pose in front of you as well."

At The Late Show, musical director Jon Batiste went the other direction and created a whole song about Harris, his MVP, "most vice presidential."

The Late Show also mocked Jared Kushner's comments on Black people not wanting success. You can watch that below. Peter Weber

President Trump flew into Omaha, Nebraska, on Tuesday night to hold a rally in the state's 2nd Congressional District, which has its own single Electoral College vote and also abuts western Iowa, a state where he is essentially tied with Democrat Joe Biden. Trump spoke for about 47 minutes at Eppley Airfield. "A reporter estimated that more than 6,000 people attended the rally," the Omaha World-Herald reports. "Law enforcement and campaign sources estimated the crowd above 10,000. Trump said the crowd was 29,000."

Trump's speech went fine. The aftermath, not so much.

Fox News correspondent Jeff Paul posted some video from 90 minutes after the rally ended, pegging the temperature outside at about 32 degrees, freezing.

"The event itself seemed poorly planned from the beginning," Paige Godden reports at Iowa Starting Line. The parking lots were full, the shuttle buses for the 3.5-mile ride to the rally venue intermittent, and the lines long everywhere. People were still waiting to get in even after Trump started speaking, Godden writes. "Some started shouting for the line to move faster, and some began saying they needed to use the restroom and threatened to relieve themselves while waiting in line." Read more at Iowa Starting Line.

"Guys, we are just one week away from Election Day," Jimmy Fallon said on Tuesday's Tonight Show. "I can't believe it's that soon — I mean, it feels like the last four years have just really flown by." Actually, "seven days is still a lot of time: If you get in line to vote now, there's a really good chance you'll make it to the front by Nov. 3," he joked. "Over 65 million have already voted, and thanks to the Supreme Court, almost three million of those will be counted."

President Trump and Joe Biden are flying around the country, but especially Trump. "Usually the only people who travel this much are salesmen and fugitives," Fallon said. "I'm not sure Trump's rallies are really moving the needle. It's hard to convince voters you deserve a second term when your speech has 42 mentions of the word 'plague.'"

Yes, "the biggest news in the election is the coronavirus, and things are only getting plague-ier," Stephen Colbert said on The Late Show. Things are especially dire in swing states, where Trump's COVID-19 approval ratings are slipping and people are mad about "his super-spreader rallies," he added. "Apparently, voters are not responding to his campaign's closing message: Let the maskless man spit on you!" He cut together Biden and Trump making their very different "closing arguments to the American voters."

With a week until voting ends, "I feel like I'm waiting for the results of a biopsy right now — that's the mood I'm in," Jimmy Kimmel said on Kimmel Live. "Donald Trump's doing his best to keep the COVID going. He had three rallies today, he's got two more tomorrow, despite the fact that at his rallies in Minnesota last month, each one of those rallies was the site of a virus outbreak," state officials determined. "I remember the good old days when the only disease we worried about Donald Trump spreading was syphilis," he joked. But at least former President Barak Obama, stumping for Biden, "seems to be having fun with this"

"Often on this show, we mock Donald Trump for going off the rails while speaking, but Obama proved today it can happen to the best of us," James Corden said at The Late Late Show. Except his entire band got the Popeye reference that went over Corden's head, and you can watch that — plus a pretty solid Trump-Amish joke — below. Peter Weber

The Senate adjourned Monday night until the week after the Nov. 3 election, officially ending all hopes of COVID-19 economic relief legislation being passed before voting ends, and probably much longer. Senate Majority Leader Mitch McConnell (R-Ky.) had made clear he did not want to vote on a roughly $2 trillion package being negotiated by House Speaker Nancy Pelosi (D-Calif.) and, on behalf of President Trump, Treasury Secretary Steven Mnuchin. Trump had sent mixed messages, but tended toward enthusiasm for an expensive package. Pelosi threw in the towel Tuesday.

"For a long time now, congressional Democrats have laid out a strategic plan to crush the virus," Pelosi said in a letter to House Democrats. "The White House and Mitch McConnell have resisted, and on Sunday, Mark Meadows told us why saying 'We're not going to control the pandemic.'" The White House, she added, "has failed miserably — not by accident, but by decision" — and while the House will "continue to put pen to paper" on legislation, "the president's words only have meaning if he can get Mitch McConnell to take his hand off the pause button."

The president's words on Tuesday were to accuse Pelosi of being "interested in bailing out badly-run, crime-ridden Democrat cities and states," not "helping the people," and promising: "After the election, we will get the best stimulus package you have ever seen." U.S. stock indexes dropped markedly again Tuesday on fading hopes for a financial stimulus and rapidly rising COVID-19 infections. Peter Weber
