Will anything change following the first primary debate?
I think Geoffrey has this exactly right: It seemed a little like the candidates were playing pretend tonight by ignoring Trump. But they’re in a tough position, politically. Someone needs to go after Trump in order to open up space for another potential nominee, but going after Trump is also extremely unattractive to GOP voters. That combination keeps Trump in a strong position as the front-runner.
At this point, the question isn’t who will be the alternative to Trump, but whether Republicans will produce an alternative nominee to Trump at all. DeSantis needed to prove tonight that he could live up to the initial hype around him, that he was Republicans’ clear alternative to nominating Trump. But there didn’t seem to be a breakout moment for him. A handful of others — like Haley and Pence — had some strong moments, but we’ll have to wait for polling to see whether those actually resonated with voters. Otherwise, it’s more of the same – which is good news for Trump.
