What Went Down At The ABC Republican Debate

According to Betfair, Rubio’s chances of winning the Republican nomination have declined to about 52 percent from 55 percent before the debate began. That seems reasonable enough. I thought he was really, really bad in the first half-hour of the debate. However, (i) it’s not that easy to judge how people at home are seeing things and (ii) the other frontrunners, Donald Trump and Ted Cruz, haven’t had a very good night either.

Nate, you’ve been very bullish on Rubio’s chances since early 2015. How bad is tonight?
