I really do not think the GOP will win races if this reflects the mindset of the national party leaders. Are you serious that Palin represents what every successful Republican candidate should be? Do intelligence and interest in larger domestic and international matters count for nothing? Stop kidding yourself - she was not a real conservative. She was, at best, a religious ideologue who was more than willing to benefit from government largesse (bridges to nowhere, the road to the bridge to nowhere, redistribution of oil revenues). Once she passed the theological test all her faults would be covered by the GOP spin machine and right wing radio yakkers.
Honestly, aside from Palin's magnetic personality, she contributed nothing to the ticket. If the GOP aspires to put up empty suit candidates because they look good on TV and wear their ignorance like a badge of honor, they will spend quite a lot of time in the political wilderness -- especially in times when people live in fear of losing their jobs and their homes.
