I worry that you will be right, but the evidence is unclear. Trump is almost certainly a whole lot better than Jeb/Rubio/Christie, and that's a big plus. I'm also convinced that he'd be a strong general election candidate. Cruz is my first choice, but I'm having trouble finding a viable second (among those in the race) who is better than Trump. I don't like Trump's touchback Amnesty much better than Rubio/Bush's straight Amnesty, but Trump's campaign is otherwise mostly based on good ideas.
See my #106. I wanted to respond to your reply, but duty calls...aka...work!
