I think the problems that caused her to resign as governor will only increase were she to win the Presidency. No one has given me any information that indicates anything has changed in her life since she resigned, so that says to me she isn't up to the Presidency. I'd love to have her as President, but only if the issues that caused her resignation are resolved.
Then, tell me who do you think is “up to the Presidency.”
It's a little early to say. Not many have declared their candidacy at this point. :)
Sarah Palin made a strong case in her book for stepping down from the governorship. This is why that issue has been moved off the table. Those who raise that issue will have guaranteed their loss in an election.
I think we should be building the momentum for a presidential candidate right now.
