Brilliant, you say:
One of the main reasons I will not be voting for Trump even if he’s nominated is that I don’t think he’s a Republican.
That would make sense as a stand-alone, however, in context it doesn't fit logically. In a very real sense, not voting for Trump is a vote for his opponent, Hillary, and you will personally own the results; i.e., there is no middle ground.
How do you define Hillary?
With all we know about each do you actually believe she offers you, indeed the nation, a better choice?
That was 4 months ago, and I have since decided to vote for Trump because Hillary is the alternative. However, I don’t think it’s going to make a difference. There are too many who made the same vow who are not on board with Trump. I have voted straight Republican in every election since 1980, and I know a lot of Republicans. I also know that a lot of them have told me they won’t be voting Republican this year, though. I don’t think you can blame that on the GOPe.
