The strategy is to hold your ammunition until the opposition is within range. Blowing your load at a distance would only allow a better candidate to fill the role.
You want to have your opposition be the most vulnerable candidate so you can blast hard with new material and blindside them. If you show your hand now, the most vulnerable will either have healed the wounds and be battle hardened or be replaced by another strong candidate. Timing is everything.
Political strategy is not rocket science.
Trump is such a great strategist that I think he will purposely let some of this stuff trickle out after he is rolling and has won a few primaries or has the nomination locked in.
His whole tiff with Megan Kelly in the first debate was to position himself in favorable light with the main stream media.
Who does the main stream media hate more than a Republican candidate? Fox network that started a few years ago and took all their viewers and ad revenue! So Trump’s tiff with Fox opened the door for him to mainstream. Trump is by far one of the best strategists I have ever observed. I just don’t trust the purity of his motive.
Trump was closing hundred million dollar deals by playing hardball with the big guys when he was in his twenties! If you read about his deal making ability, this guy is nothing short of a genius.
Bush and his backers would love to have seen Trump eliminated early. Now it’s too late.
