Trump is nearly 70, has no organization, and will rapidly become a political irrelevance if he loses. Then we'll all sit muttering in our tiny little factions about how it was other conservatives who screwed us over, while the country burns.
As much as I detest Trump (and an increasing number of intolerant Trumpers), I'm still voting for the guy if he's the nominee. Feel free to sit in your smugness and watch the country go down the drain, though, because obviously your pride is worth more to you.
