Is McCain really too old to be President?

Ronald Regan, the greatest president of all-time was older than McCain when he ran for reelection. It seems to me Democrats want to make age an issue only to try and drag Palin into the fray. Why aren't Democrats talking about age being an issue with Obama as in being too young and inexperienced? Also, Democrats seem to be infatuated with Palim's so called fundamental attachments to Christian beliefs, but Obama is the one who had a two decade intimate relationship with a nut job Christian black power pastor. It is obvious Democrats are grasping at straws and coming up empty handed!
