Now I'm thinking Trump does not actually plan to run. I just can't imagine anyone who seriously intends to run for President giving a speech laced with vulgarities. It's almost as if he felt safe doing so because he knows he's not actually going to run, and that he's accomplishing what he wanted to do by being a general instigator and playing off the ambiguity surrounding his intentions.
I could be wrong, I just don't think anyone could seriously conclude that being the "Happy Gilmore" of presidential candidates is a winning strategy.
