This Abridge News topic aggregates four unique arguments on different sides of the debate. Here are the quick facts to get you started:

THE QUICK FACTS

On Monday, the Associated Press reported that former Ohio governor and Republican presidential candidate John Kasich would speak at the Democratic National Convention in August. For one party to dragoon a notable from the other side into endorsing its presidential candidate is hardly unprecedented. And most of the time, it makes no difference.

Conservatives are always looking for converts, the old saying goes, while liberals are always looking for heretics. This would explain why so many of each are so angry right now. Joe Biden’s campaign has attracted the support of a small clique of Republican converts: the Lincoln Project, a boutique collection of anti-Trump Republicans, as well as former Ohio governor John Kasich, who confirmed yesterday he will endorse Biden at the Democratic convention.

There are honorable and honest ways to oppose your own party, and to leave it. As a conservative who took the Never-Trump path and voted for Evan McMullin in 2016, I will grant the good faith of a lot of lifelong Republicans and conservatives who believe that they must support Donald Trump’s opponent on the grounds that Trump is unfit for office. And people are entitled to change their minds about what they believe. But it is also important to be honest about what you’re doing, and to take responsibility for your own choices. Neither the Lincoln Project nor John Kasich is doing this.

George Conway’s Lincoln Project hits Trump and praises Biden in a blistering new video.

A conservative group critical of President Donald Trump is going on the attack with a new ad endorsing former Vice President Joe Biden for November’s election.

The spot from The Lincoln Project, titled “Ready,” lauds Biden as “a bipartisan leader who puts good ideas ahead of party politics” and praises his strength and character.

“America knows Joe Biden,” the narrator states. “He is the man for this moment.”
