The second Republican debate of the 2024 presidential primary, taking place at the Ronald Reagan Presidential Library, has just come to an end.

The affair was more raucous than the first debate, which took place over a month ago. Candidates interrupted one another much more regularly and several — most notably former Vice President Mike Pence and former New Jersey Gov. Chris Christie — have directly criticized front-runner Donald Trump, who elected not to show up tonight. The two candidates from South Carolina, former U.N. ambassador Nikki Haley and Sen. Tim Scott, went after one another for their records on spending, and seemingly everyone who had the chance to take a shot at entrepreneur Vivek Ramaswamy did so.

Instead of participating in tonight’s debate, Trump opted to give a speech in Detroit, where autoworkers are on strike against the Big Three automakers. In a recent Morning Consult poll, 54 percent of Americans said they support the strike by the United Auto Workers against General Motors, Ford and Stellantis, while just 18 percent were opposed and 28 percent didn’t have an opinion.

What 538 is watching for tonight: Trump and Michigan

Tonight, I’m watching the debate from Michigan, where I’m covering a split within the GOP. I’m looking for signs of where the party is breaking with Trump and where they’re still loyal to him. I’m also listening for the candidates’ positions on issues Republican voters in this state say they care about. They’re still angry over the COVID-19 shutdowns, they’re mad about electric cars, which they say will cost auto worker jobs, and they’re worried about the economy. That’s especially true with United Auto Workers workers striking in this state. This week, Biden joined the picket line and Trump will visit a nonunion plant.

What 538 is watching for tonight: Ramaswamy

I'm closely monitoring Vivek Ramaswamy. The self-proclaimed outsider made a big splash during the last debate, garnering more media attention and generating higher Google search interest than his rivals. This triggered speculation that he might experience an upswing in the polls. However, his numbers have exhibited a consistent downward trend over the last month. It's plausible that the very characteristic that initially captivated debate viewers — his confrontational and too-smart-to-be-here style of arguing — may have, ironically, alienated the average Republican voter. I'll be looking for any shifts in his rhetorical approach or substantive positions during tonight's proceedings. Like his fellow candidates, Ramaswamy needs a substantial strategic maneuver to reshape the trajectory of his campaign.
