Voters in Ohio's 12th congressional district are electing a replacement for former Rep. Pat Tiberi (R) on Tuesday. President Trump won the district by 11 points and Republicans have held the seat almost uninterrupted since 1920 — Ohio Gov. John Kasich (R) unseated the rare one-term Democrat in 1982 and easily kept the seat until 2000, when Tiberi took over — but polls show an unexpectedly tight race between Republican state Sen. Troy Balderson, 56, and Democrat Danny O'Connor, 31.

Republicans are pulling out all the stops. Trump held a rally for Balderson in Ohio on Saturday and tweeted his endorsement Sunday, Vice President Mike Pence has campaigned for him twice, House Speaker Paul Ryan (R-Wis.) made a campaign stop for Balderson, and Kasich endorsed him. If O'Connor wins in the northern Columbus suburbs, Democrats will plausibly claim momentum going into the midterms. National Republicans, who've spent $3.5 million on TV ads attacking O'Connor and another half-million on get-out-the-vote efforts, are working to keep the seat and deprive Democrats of a talking point. This is the last competitive election before the November midterms. Peter Weber

President Trump revisited familiar complaints on Twitter Sunday, reiterating his animosity toward a variety of people on a variety of topics.

He began with a gripe about the media, particularly Saturday Night Live, which opened the night before with Alec Baldwin reprising his role as the president in a sketch parodying the holiday classic It's a Wonderful Life.

Alas for Trump, satire is indeed legal.

He soon moved on to the subject of former FBI agent Peter Strzok and former FBI lawyer Lisa Page. While Trump claimed in tweets Saturday night and Sunday morning that "19,000 Texts between [the two] were just reported as being wiped clean," the reality is Politico reported Thursday that about 19,000 previously missing texts were recovered by the Department of Justice investigation into Strzok and Page.

Trump next made a convoluted non sequitur about the FBI's warranted search of an office belonging to his former personal attorney, Michael Cohen:

On immigration, Trump at once condemned the Obama administration for separating some migrant families while boasting of his own separation policy. And finally, the president said he would review the case of Matt Golsteyn, a former Green Beret who has been charged by the Army with premeditated murder for his admitted role in killing an Afghan man he claimed was a Taliban bomb maker.

British Prime Minister Theresa May on Sunday pushed back on calls for a second referendum on Brexit, the United Kingdom's exit from the European Union.

May particularly condemned remarks from former Prime Minister Tony Blair, who said this week a new vote should be considered if "none of the other options work." May accused Blair of "seek[ing] to undermine our negotiations by advocating for a second referendum," arguing "Parliament has a democratic duty to deliver what the British people voted for."

May's proposed Brexit deal with the EU has stalled, lacking support to pass a House of Commons vote. Bonnie Kristian

The North Korean government on Sunday issued a typically dramatic statement condemning the United States' sanction regime and suggesting denuclearization plans are in jeopardy.

Pyongyang accused the U.S. State Department of being "bent on bringing [North Korea]-U.S. relations back to the status of last year which was marked by exchanges of fire," warning that additional U.S. sanctions would be America's "greatest miscalculation" and would "block the path to denuclearization on the Korean peninsula forever."

This comes as Pyongyang observes the seventh anniversary of the death of former leader Kim Jong Il and the rise to power of his son, current leader Kim Jong Un. Bonnie Kristian

Negotiators representing nearly 200 nations in Katowice, Poland, on Saturday agreed to universal greenhouse gas emissions limits intended to mitigate global climate change.

"It is not easy to find agreement on a deal so specific and technical," said Polish economist Michal Kurtyka, who is leading the United Nations negotiations. "Through this package you have made a thousand little steps forward together," he told the assembled delegates. "You can feel proud."

U.S. negotiators sought to label coal a possible source of clean energy but also pushed for transparency and rules which apply equally to all participant nations. "Overall, the U.S. role here has been somewhat schizophrenic — pushing coal and dissing science on the one hand, but also working hard in the room for strong transparency rules," Elliot Diringer of the Center for Climate and Energy Solutions told The Associated Press. "[T]he U.S. pushed harder than nearly anyone else for transparency rules that put all countries under the same system, and it's largely succeeded." Bonnie Kristian

Saturday Night Live's President Trump (Alec Baldwin) was in a pensive mood on the White House balcony when an angel named Clarence (Kenan Thompson) showed up, straight from helping George Bailey in It's a Wonderful Life, to help Trump see the world as it would have been had he never been president.

Where a world without George Bailey was grim indeed, a world where Trump lost in 2016 is pretty great — for everyone. White House counselor Kellyanne Conway (Kate McKinnon) is on good terms with her husband; Supreme Court Justice Brett Kavanaugh (Matt Damon) is a regular guy having a great time with his beers and calendars; Trump's former personal attorney, Michael Cohen (Ben Stiller), is his current personal attorney who is not headed to prison; and Special Counsel Robert Mueller (Robert De Niro) is enjoying a pleasant old age with his grandchildren.

Alas, Trump doesn't learn the lesson Clarence hopes. Watch the full sketch below. Bonnie Kristian

Acting White House Chief of Staff Mick Mulvaney's past criticisms of President Trump have received new attention over the weekend following Friday's news of Mulvaney's acceptance of his third role in the Trump administration.

After the 2016 discovery of Trump's lewd Access Hollywood remarks, Mulvaney wrote on his congressional Facebook page that Trump is "not a very good person," and his words were "disgusting and indefensible." In a debate with his Democratic rival for that year's election, Mulvaney similarly said he was supporting Trump despite thinking "he's a terrible human being" because "the choice on the other side is just as bad."

Despite this past antipathy, a Politico report late Saturday describes Mulvaney as an eager recipient of his new role. "He would have given up a very valuable appendage to get that job," an unnamed Republican close to the Trump White House claimed.

Politico's sources said Washingtonian assessment of Mulvaney's aims in rising through the ranks of the Trump administration varies. While "some conservatives on the Hill see him as a sellout, a ladder-climber who puts career advancement over principle," others "argue that he's done the best he can given the president he serves and advanced conservative priorities where he can."
