A few days before the Nevada caucuses, Sen. Bernie Sanders (I-Vt.) has taken a 12 percentage point lead in the Democratic presidential contest, according to an NPR/PBS NewsHour/Marist poll released Tuesday morning. Sanders has the support of 31 percent of Democrats and Democratic-leaning independents, up 9 points from the last Marist poll in December, but coming in at No. 2 is former New York City Mayor Michael Bloomberg, at 19 percent. That's a 15-point jump since December.

This poll qualifies Bloomberg to participate in Wednesday's Democratic debate, though Bloomberg won't be on the ballot in Saturday's caucuses. Bloomberg's campaign said he plans to participate if he qualifies. The billionaire media tycoon built up his poll numbers with the help of more than $400 million of his personal fortune and lots of advertising. He and the other candidates, especially Sanders, are going after each other with increasing vigor.

Former Vice President Joe Biden comes in third place in the poll at 15 percent, down 9 points since December, followed by Sen. Elizabeth Warren (D-Mass.) at 12 percent (a drop of 5 points), Sen. Amy Klobuchar (D-Minn.) at 9 percent (down 4 points), and former South Bend Mayor Pete Buttigieg at 8 percent (down from 13 percent). Buttigieg narrowly leads in delegates after strong showings in Iowa and New Hampshire.

All of the candidates beat President Trump in a hypothetical head-to-head matchups, with Biden enjoying the biggest lead, followed by Bloomberg, Sanders, Klobuchar and Buttigieg, and Warren. Sanders leads among most categories except black voters — he's a close second to Biden — moderates, and voters over 45; Bloomberg gets the most support among those last two groups and is No. 3 with black voters.

Marist conducted the poll Feb. 13-16 among 1,416 U.S. adults, including 527 Democrats and leaners. The entire poll, including the head-to-heads with Trump, has a margin of error of ±3.7 percentage points; the Democratic rankings have a margin of error of ±5.4 points. Peter Weber

Two wind-driven brush fires in Orange County, California, have scorched more than 10,000 acres combined and forced at least 100,000 residents to evacuate from their homes.

The Silverado fire broke out in Irvine on Monday morning, and by evening had scorched 7,200 acres. Orange County Fire Authority Chief Brian Fennessy told the Los Angeles Times that a 26-year-old firefighter and a 31-year-old firefighter both sustained second- and third-degree burns while battling the blaze, and are now intubated at a local hospital. "They're gravely injured," he said. "We're doing all we can for them."

On Monday evening, Southern California Edison told the state's Public Utilities Commission it is investigating whether its equipment may have sparked the Silverado fire. So far, no homes have been reported destroyed in the blaze.

A second blaze, the Blue Ridge fire near Yorba Linda, has burned 3,000 acres and destroyed one home. The dry Santa Ana winds are fanning the flames, and gusts of up to 70 mph were recorded in Orange County on Monday. Relative humidity was at five percent, "which is bone-dry," National Weather Service meteorologist Dan Gregoria told the Times, and the dry air combined with high winds is "creating these critical fire conditions."

White House Press Secretary Kayleigh McEnany is walking back comments she made in 2015, when she called Democratic presidential nominee Joe Biden, then the vice president, "a man of the people" who is "funny and likable."

CNN's KFile reports that in August 2015, McEnany appeared on New York's AM970 to discuss what would happen if Donald Trump became the Republican presidential nominee and Biden, who was mulling a run for president, became the candidate for the Democrats.

McEnany said this would be "a problem" for the GOP, because "Joe Biden, one of the things he is remarkable at is really kind of being a man of the people and resonating with middle class voters. ... His gaffes, as much as we make fun of them, to a certain extent they make him look human." With Biden against Trump, "I think the juxtaposition of kind of the man of the people and kind of this tycoon is a problem," she added. Earlier that week, CNN reports, McEnany was on Fox Business Network, and said Biden was "funny and likable and can resonate with the middle class, he really can speak to the average, everyday American, versus Hillary Clinton, who's cold and somber."

After the 2016 election, McEnany became a spokeswoman for the Republican National Committee and joined the Trump team, and has blasted Biden at every opportunity, calling him a "radical socialist" and "sleepy." When CNN asked her to comment on her 2015 remarks about Biden, she accused him of being corrupt and called him "an empty vessel for the liberal elites and far left."

McEnany has also changed her tune when it comes to Trump; in 2015, after Trump said Mexico was sending "rapists" to the U.S., she said on CNN "a racist statement is a racist statement. I don't like what Donald Trump has said." In another interview on CNN, she called Trump "a Republican in name only" and said she didn't "want to claim this guy." As Trump's poll numbers began to go up, McEnany had a change of heart, and defended Trump's comments about Mexican immigrants. After becoming press secretary earlier this year, she explained away her earlier criticisms of Trump, saying she "very quickly came around and supported the president." Catherine Garcia

After the Senate voted on Monday night to confirm Amy Coney Barrett as a Supreme Court justice, she spoke at a White House event, saying she was "truly honored and humbled" to be selected for the position.

Before Barrett spoke, Justice Clarence Thomas administered the constitutional oath to her; on Tuesday, Chief Justice John Roberts will administer the judicial oath during a private ceremony. Several Republican senators attended the event, held outside on the White House's South Lawn.

During her remarks, Barrett said it is "the job of a senator to pursue her policy preferences" but "it is the job of a judge to resist her policy preferences," and "the oath that I have solemnly taken tonight means at its core that I will do my job without any fear or favor, and that I will do so independently of both the political branches and of my own preferences. I love the Constitution and the democratic republic that it establishes, and I will devote myself to preserving it." Catherine Garcia

The Supreme Court on Monday night refused to reinstate a Wisconsin federal court's order to extend the deadline for absentee ballots in the state.

The district court's order was put on hold by a federal appeals court. The justices split 5-3, with the conservative justices opposing the extension, which would have let election officials count mail-in ballots as long as they are received up to six days after the Nov. 3 election.

Democrats have argued that because of the coronavirus pandemic, more voters will use mail-in ballots and there needs to be additional time to count them all. Wisconsin is seeing a surge in coronavirus cases, and hospitalizations have reached a record high.

In her dissent, Justice Elena Kagan wrote that the Supreme Court "has failed to adequately protect the nation's voters," adding that in April, Wisconsin allowed a six-day extension during primary voting, and about 80,000 ballots were received on the day after the primary election. Justice Neil Gorsuch said while "no one doubts that conducting a national election amid a pandemic poses serious challenges," that does not mean "individual judges may improvise with their own election rules in place of those the people's representatives have adopted."

The Senate on Monday night confirmed Amy Coney Barrett as the 115th justice to the Supreme Court, succeeding the late liberal icon Justice Ruth Bader Ginsburg.

It was a 52-48 vote, with Sen. Susan Collins of Maine the only Republican to join Democrats in opposing Barrett's confirmation. Barrett, 48, was President Trump's third nominee to the Supreme Court, and increases the conservative majority on the court to 6-3.

Senate Majority Leader Mitch McConnell (R-Ky.) moved at lightning speed to ensure Barrett was confirmed ahead of the Nov. 3 election, despite refusing to allow a vote in 2016 when former President Barack Obama nominated Judge Merrick Garland following the death of Justice Antonin Scalia in February. At that time, McConnell said the next Supreme Court justice should be selected by the next president, elected in November. Catherine Garcia

Zeta, the earliest ever 27th named storm of the Atlantic season, strengthened to a hurricane Monday afternoon, and is centered about 90 miles southeast of Mexico's Cozumel island, the U.S. National Hurricane Center said.

Zeta has maximum sustained winds of 80 mph and is moving northwest at 10 mph. Forecasters expect the storm to make its way over the Yucatan Peninsula late Monday before moving into the Gulf of Mexico. Zeta will likely approach the Gulf Coast by Wednesday, but could weaken by that point.

The storm could bring four to eight inches of rain to Mexico, parts of Cuba, and the Cayman Islands, the U.S. National Hurricane Center said, and could make landfall in the United States anywhere from Louisiana to Florida's Panhandle. Zeta is the 11th hurricane of the 2020 season; during an average season, there are six hurricanes and 12 named storms, The Associated Press reports. Catherine Garcia
