His problem is he leads like a loose, poorly directed cannon.
None of the milquetoast contenders we currently see have that type of temperament.
Palin perhaps excepted. But you're right, we have a real serious problem in finding the candidate to beat Obama.
While I applaud Palin and hope she continues to use the platform she has, I don't think she has “it”.
As things continue to worsen the American people will demand leadership which will lead to: a) re-elect Obama which will embolden the left to push farther down the road to liberal fascism and corporatism which will last for an extended period, or... b) a strong Republican will emerge who will demand respect from other nations and unleash the American entrepreneurial spirit much like Reagan did.
The squishy middle is about to evaporate.
