No, I am unsure that she is going to run. If she runs, she will win the nomination. Of that I am confident.
Reality says it works the other way around. (Think Sharon Angle, Christine O'Donnell, Joe Miller, etc)
Palin has won elections before. The only reason Obama didn't take all 57 states is because McCain had Palin on his ticket.
I am pretty sure that America is not ready for a reality-show/tabloid president.
And my hope is that certain portions of the conservative movement don’t get one nominated in the Republican party.
