Kurt Schleiter (sp?) over at Townhall.com had a column last week, IIRC, where he said that if Trump loses, he will forever be known as a 'loser,' and not the guy who built all sorts of buildings in NYC. It would be a massive hit to his ego. Coincidentally, right about that time, Kellyanne Conway came aboard as his campaign manager--and she seems to have a modicum of discipline and sanity to Trump and the campaign. I think that Conway said pretty much what Schleiter wrote in his column. This time, he's actually listening to the advice.
Now, if he'd stop using his Twitter account as much as he does, and screwing himself up that way . . . !
