There's only ONE conservative running who passes the Free Republic smell test, and that's Ted Cruz. But can a Republican junior Senator with less than a single term in office under his belt, go all the way to the White House on his very first attempt? Not even slightly likely.
The Clinton/Bush/Rove/Leftmedia/GOP-Dem cartel will bury every other candidate in the race to come, except for Donald Trump. As a billionaire outsider, he can't be controlled, can't be bought, can't be scared off, can't be bullied, can't be silenced, and can't be stopped, just as long as he maintains his personal quest to become president.
On January 20th, 2017, a new president is going to be sworn in. It will be Jeb Bush, Hillary Clinton, or Donald Trump. Those are your choices. There are NO others.
Choose now.
My, my, you have such powers of prognostication.
On a more serious note, if the only prevention for Clinton or Bush is Trump, we are already cooked. The Donald is not a solution, he is, perhaps, an even bigger disaster waiting to happen. Why? Because if he is, as you intimate, answerable only to himself, where would that leave us if - when! - he goes out of control?
