Using my Fox News Election Headquarters app, I rated Marco Rubio a +10 in the debate. He is the candidate I have decided to support now since Scott Walker dropped out. His performance at the debate was amazing. He called out the moderators for getting his tax plan wrong and told the truth about Hillary Clinton and the mainstream media. He was on point every time. I can easily see him getting a bump in the polls after this performance. I'm not certain this performance will take him all the way to first place, but it is a possibility.
Donald Trump (+6) and Ben Carson (+4) were not the spotlights of the night, but I don't know if this will hurt them. Aside from an argument with John Kasich, Trump didn't gather all the attention. Part of it might be that no other candidate attacked him. He wasn't specific, but part of that can be blamed on the moderators. Overall, there wasn't anything memorable from him. Ben Carson continued in the same style he has always been. I think people generally like how calm he is, but at the same time other candidates got roaring applause from terrific statements. Since his style is working, I'm also skeptical that his poll numbers will fall.
Carly Fiorina had a good performance during this debate and I got a +7 with her. While she didn't have a moment from the last debate where she propelled from criticizing Planned Parenthood, she still made some good points with details. I don't think her poll numbers will surge, but they might go up. Ted Cruz got a +6 from me. Cruz's performance comes right behind Rubio's. The Texas senator was the first candidate to attack the moderators and he was clearly very popular throughout the night. Chris Christie's performance was pretty good (+7). His comment on fantasy football was especially popular.
Mike Huckabee (+4) and Rand Paul (+2) seemed to fade for most of the debate. Both of them provided generally positive rhetoric, but they did not stand out. I thought that John Kasich (+4) and Jeb Bush (+2) did even worse. Kasich seemed to be the "mad as hell" candidate, but that somewhat backfired. I don't remember any big moments from him, except for engaging Trump at the beginning. Bush is, without a doubt, the losing candidate of this debate. Like Huckabee and Paul, he seemed to fade for most of the debate. His most memorable performance was a lousy attack on Rubio in which he criticized the Florida senator for a bad attendance record. Rubio's strong response was to point out the historical norm for senators who run for president. He also made note of Bush's endorsement to Senator John McCain in 2008, who also had low Senate appearances during his presidential run.
Concluding, I think Bush, Huckabee, Paul, and Kasich are in deep trouble. Bush's support continues to decrease and it isn't hard to believe that donors are getting concerned. The other three were never high in the polls, but the next debate in Milwaukee requires a 2.5 percent showing. That should concern them. I think Trump and Carson will continue to have the highest support, but they probably will decrease with rising numbers from Cruz and Rubio.
