Trump's spikes seemed to happen during Bush and Carson's drops and they don't have much in common with each other whether you're looking at education, personality, anything. Now there's 5 weeks to go and Trump has been in the lead since August. It does look like Trump will win some states like Iowa before the rest of the Republicans coalesce around a less radical candidate but that will be a drawn out battle. And I'm thinking it's good to be prepared for the reality that Trump might be nominated.
That poll is both hilarious and sad at the same time.
Sure, it's nice that college educated Republican women have shown literally 0% support for Trump.
But that's completely nullified by their 63% support for Carson. 
I don't have a lot of love for the GOP candidates, but Carson really rubs me the wrong way. With his phony humility combined with a stunning ignorance about foreign affairs, how could anyone support him other than from a purely opportunist Realpolitik stance?
Doesn't he have the most individual donors of the Republican field? Maybe there's a lot of old people who love their doctors. He and Cruz are probably the most well-educated candidates but I don't think that matters much, most Republicans are probably resigned to the fact that this election is about how well they fail.
