Trump Doing Better w/Liberals, Moderates and Democrats than Jeb Bush
The consultant class messaging is that Trump would scare away far too many moderate and minority voters. So far there's no sign of that. In matchups against Hillary, the latest CNN poll shows Trump and Jeb Bush getting the same amount of the non-white vote (very little).
It also shows Trump having a slight lead among liberals, moderates and Democrats. The amount is within the margin of error and insignificant, but it shows that the claim that Trump will alienate middle of road voters isn't currently being reflected in polls. Or rather, Trump is not any more alienating than Republican candidates to a demographic that is thoroughly media injected.
Trump however does somewhat worse than Jeb Bush with independent voters and he appears to move a few percent of Republican leaning voters to Clinton.
Trump does much better with the 35 to 49 age group voters than Jeb Bush. His performance is terrible with younger voters though. And there is a troubling warning sign in the poll. Trump performs worse than Jeb Bush among under $50K voters, the people he's supposed to be appealing to with immigration populism.
Trump's biggest problem appears to be the South. Clinton and Bush are neck and neck there. With Trump, Hillary has a solid poll lead.
He does pick up more Tea Party support than Jeb. And Trump does significantly better in the Northeast than Bush, but that may matter less in an election. Trump is somewhat better in urban areas, but much worse in rural areas. It looks like that may be a hole in his campaign that he needs to fix.
