Palin, with one call, can bring in tens of millions to jump-start a political party. But, will she?
She is a private citizen with bills to pay and mouths to feed, so her decisions must make financial sense for her. Starting an organized political party might mean a lot of restrictions on her (long term) financial viability. Once she is stuck with a political party, especially the one she helps build, then all her eggs will be in one basket and she will lose a lot of flexibility.
I have sent Sarah Palin more money than ANY other politician. I will NOT follow her out of the Republican party.
