I think Trump knows he might very well get the Presidency...but I’m of the opinion currently he may be rethinking if he ‘really’ wants it and or if he can actually accomplish what he’s saying he’ll do. He may have bitten off more than he can chew as he’s become more “informed” of what it will certainly take to handle running a country. Might be getting cold feet.
Question is, if Trump does not fill the shoes, who will? An establishment lackey? I am hoping there is someone out there to heed the call. A dark horse.
