I agree with Jo Deslaurier. I think that she is enjoying her new found fame and fortune, and I don't think that she will want to give it up at this point in time. If she is going make a run for president, I think maybe 2016, or even 2020. If she did run for president in 2012, I don't really think that she would get the nomination. The republican party needs to have someone with more experience who can go toe to toe with Obama and win.
Personally, I like Sarah Palin. I think she is very shrewd and clever and not as dumb as some people think. As the old saying goes, "Never underestimate your opponent".
