The media pundits all had their own opinion on who won last Wednesday's GOP debate, but that's not nearly as important as who the Republican voters think won the debate. And following that debate, the Gravis Marketing Poll queried 1,504 registered Republicans on who they thought won the debate. The survey has a margin of error of 2.5 points, and the results are shown in the chart above.
It looks like four candidates did themselves some good in that debate -- Donald Trump, Marco Rubio, Ted Cruz, and Ben Carson. All four had a double-digit amount saying they won the debate (with the largest percentage going to Trump), and only a very small percentage saying they had lost.
Three candidates seem to have hurt themselves with their debate performance -- John Katich, Rand Paul, and Jeb Bush. They all had only 3% or less saying they won, while having a double-digit percentage saying they lost the debate. I expect all three to hang on for a while longer, but their campaigns seem to be fizzling out -- and if they can't turn that around soon, will have to drop out. This is especially surprising of Jeb Bush (who once was the favorite for the nomination).
