Republican debate highlights and analysis: Candidates squabble in Simi Valley

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.

I’m monitoring Pence tonight, and I’ve got to be honest: I don’t know how much he can do to increase his standing in the primary other than hope that other candidates implode. During the last debate, he had plenty of speaking time and, given Trump’s hatred for his former vice president, a pretty strong reception from the Fox News crowd. But still, nothing substantially changed. Voters expected him to give an average performance, and he pretty much delivered. He’s averaging less than 5 percent in national primary polling.

It’s not clear where Pence has room to grow. He’s better known than any candidate on tonight’s debate stage, and voters seem to have decided how they feel about him. If he’s a second-choice to similar candidates — others who, say, share his dislike of Trump but would nonetheless support him in a general election — Pence could benefit from a smaller field. So, the best thing Pence could do might just be to stay the course, continuing to get enough support to appear on a debate stage and waiting out lesser-known and underfunded candidates.

I’m watching Burgum and Scott tonight. Their task is pretty simple: Get Republican voters to notice them. According to the poll we conducted before the debate with Ipsos and The Washington Post, they’re the two most anonymous candidates on that debate stage tonight (as measured by the share of Republicans who don’t have either a favorable or unfavorable view of them). If they’re going to change that, they need to really get in the middle of some exchanges and emerge from the debate as one of the top storylines.
