If the opponents are Trump or "no abortions even in the case of rape or incest" Rubio, people will wise up.
The majority will for sure, but I think that there is a sect of the left that will hop the fence when they might not have otherwise due to how the argument over the issues have gone down. The debates have essentially been Hillary trying to argue the substance over issues like healthcare and the minimum wage and so on, with Bernie then deflecting saying "well you only say that because you have super pacs and take corporate donations". When you essentially discredit someones positions like that it makes it hard for many people I think, to vote for her. I think a lot of white leftist who are all about the campaign finance and the "screw the establishment" camp will vote for Trump just because he isn't a politician and self funding.
But just to be clear, I don't think this will be enough to win though, because you can't win on the white vote alone anymore. It won't matter how Trump repositions himself or moderates in regards to minorities. He hasn't just burned that bridge, he's nuked it. He will not be able to backpedal the blatant openly racist rhetoric. When you advocate banning all muslims, call mexicans and immigrants murders and rapists, that refugees are secret terrorist, say blacks are responsible for 80% of white deaths, etc. He has no room to come back from that.
I think he has done more damage to her than good in regards to how she stacks up for a general election. I think it won't matter in the end but I still don't like the direction we are likely headed towards or and I don't look forward towards how many people are going to make their arguments or rationalizations as to why Trump is a better choice for "the people" than Hillary due to how much campaign finance has become an issue during this primary.
