Trump would win as a third party. I know a ton of Democrats that will vote for him and it appears a lot of minorities seem to approve also. Bottom line people have had it with the Democrats and the Republicans. We have a Republican house and senate and LOOK at the deficit and the cowards we have in their now. Trump is very similar to Reagan at this stage.
Trump, is a smart man. The republican party has market value as a name. I can’t imagine him going off and starting a third party campaign, UNLESS, the nominee is Bush, then I would support him doing that.
