There are two possibilities here.
Trump is on the up and up.
Trump is not on the up and up and everyone is in on it. The Democrats, the Republicans, the Media, and folks like McCain are acting like they don’t like him to fool us.
One way or another, this election makes everything become clear, right out in the open.
We may not get what we want, but it will be impossible for them to hide who they are after November of 2016.
He is certainly shaking up the GOP and exposing their failures. And he has made a lot of people very nervous because he’s brash and a bit of a loose cannon.
Make no mistake about it, the GOP is working hard to un-do his candidacy. They hate him and will use every trick in the book to trip him up. It will be a viscous counter-attack that brings all the money and power the GOP can muster. They want him out of there because the party will have no control over him if he should become president. He refuses to play by their rules.
I hope Trump can withstand the oncoming assault of the GOP’s political operatives, but I doubt it.
That's my take. I've used the tag line below off and on since 2011.
