I was hopeful for Perry, but he is turning into a huge disappointment for the very reasons you state.
Sarah is the best one to take on the Herculean task of dismantling of the Marxist cabals which have taken over Washington and the media. Most of the rest of the candidates are apt to be either co-opted or flattened by them and it will be "game over" for our Republic. That is why she is so feared by them. They know she will go after them and tear them out root and branch.
Why go with a second fiddle when we can play with the first?
Palin is not a candidate.
