Well initially I would have agreed with that....but now that he's "tasted" the flavor of ' power' over the masses and what's in it for him he's going for the gold!
What could he possibly loose? .....This exposure does more for the "Trump Brand" than anything he could have done marketing it and at no marketing costs as the media runs with him for free.... so that's a plus for him win or loose the primary.....he can walk away still a winner as he sees himself now....while all other candidates have soaked their life and wealth into running and laid all the ground work necessary to even run.
It will be interesting, 'if' he wins the primary, will he self-fund his 'Presidential' campaign?....he may find an excuse to do otherwise considering the war chest Hillary will and does have available to her.
Besides this... Hillary would love to go up against Trump....his past will nullify hers.... so the ground the two would stand on would be level.
Sorry, I forgot the /s
lets get the spelling corrected for Christmas, eheheh. its' spelled 'lose' the primary. 'loose' is used as your belt is too loose. Okey dokey now... ('
