Palin is awesome. These guys are old news and need to just let her lead. She is a real leader.
Palin is first and foremost a social conservative; while she may be conservative on fiscal and foreign policy issues, it's obviously she's strongest on social issues. Our country has never elected a President (on either the left or right--at least in recent history) who's been most prominently known for his social positions, or who's put social issues at the forefront of his campaign. And younger voters are even more hesitant than older ones to support a candidate who's seen as socially divisive.
This isn't to say we need to nominate social liberals or even moderates (in fact, I think it's critical we remain socially conservative for the sake of the party coalition and the country), but we need to nominate candidates whose message is still focused on economic and national security issues. We need candidates who are strong enough on these issues that social moderates and liberals are willing to overlook their differences on social issues and nonetheless vote Republican.
She has made a great impression on the American people but she has allot to show me in the next four years. I will have to see substance, something more than I have so far. I don’t mean that in a bad way. My biggest area of concern would be in foreign relations and to be fair any current potential candidate still has the same things to show me. (Except Duncan Hunter.) I like Palin too, I wish her great success, I just don’t want to hand out a crown three and a half years to soon.
