No, that's not my "real beef", though nice try at setting up a strawman.
Trump is far from my preferred candidate, but Cruz wasn't either. I think both of them are weak general election candidates. A few weeks ago, I thought the best case scenario remaining was that Trump would stop the gaffes, lower his unfavorabilitye numbers, and give us a shot at winning in November. That's what I hoped would happen.
Instead, he can't stay off Twitter, and has damaged his November prospects. So now, we're left with either nominating a guy who is quickly making himself unelectable in November, or having someone else come out of a convention. And that would split the party and also make it incredibly difficult to win in November.
The bottom line for me at this point is that I want Cruz to stay in and do well because I have absolutely zero faith that Trump won't do more stupid things between now and mid-July. A contested convention is the fallback if Trump makes himself.more unelectable than he already is.
But at this piont, I'd prefer Trump to clean up his act and unite the party because I think that gives us the best chance to win in November. Unfortunately, he's given us very lite sign that he's capable of keeping his foot out of his mouth for that long.
I would prefer he had the ability to deliver a speech like Ronald Reagan but no one in politics to day even come close. I truly believe that Trump and Trump alone has even a modicum of a chance of undoing the Uniparty
