“Why is Trump plan A?”
I don’t think Trump was plan A until very recently, and I think there will be college courses in future still trying to completely answer that question. To me, it seems like he became plan A because there was no one else saying these things that the majority of Americans think and feel, something remarkable in what is supposed to be a country with a government by the people, for the people, of the people. As to why that is so, again, I think there will be college courses still trying to answer that question in coming years.
Why are you convinced he will pull out? He contemplated a run one or more times before. He was exploring one for 2012 but, partly for what he thought was for the good of the party, just got behind Romney. I watched his speech from Mar-a-Lago then, away from all the media frenzy there is now, and was impressed by his reasoning. I’m not sure if I could find it for you to watch. But after watching that, and after Trump has watched what happened over the last few years since that, I don’t see him pulling out of this one. It seems to me he’s fighting like he actually wants to win, far more than most in the field.
It will be nothing more than a footnote. Not even as big as Ross Perot.
