OR...
This could just be the republicans falling on their sword.
Mitt realized that he would most likely lose up against Hillary.
I think Hillary suggesting she would wait until this Summer to announce, told Mitt that the Clinton's were gearing up to play smart, much smarter than even Mitt had expected.
And Mitt, being the business man looking at everything from a businessman viewpoint, Mitt realized that Jeb could never win when up against Hillary, either.
So Mitt fell on his sword by quitting and then bad mouthing Jeb, and looking to future elections by suggesting the party give new blood a chance.
Knowing this new blood would also lose up against Hillary, but at least the torch would be passed to a younger republican generation.
Being the business man he is, Mitt figured he could single handed turn the parties page on the past, the Bush's, the McCain's, the Newt's, and set the landscape for new republican blood come future elections.
And even though that new blood would lose to Hillary, at least the torch would have been passed.
Giving someone like a Christie or a Rand Paul, or even a Scott Walker a path to the future.
More so, a Scott Walker.
Hillary is going to win 2016. We know that.
The economy is good, the wars are ending, people are working again, and history would be made.
Never under estimate that making history effect.
The first woman president elected theme will catch on, and who better for that job than Hillary?
Yes, as her campaign gains speed, even republican women will take to Hillary.
Hillary can cross that line.
Exactly as Obama did when republicans took a chance to make history by electing the first black president.
People LOVE making history, and able to say years from then, I WAS THERE.
