You won’t find Palin’s record to be more substantial than Jindal’s.
But Jindal doesn’t excite people. I’d vote for him based on his record but many people will only vote for the person who excites them. That’s how we got Obama. First time I saw him on tv I thought - wow! this guy is fantastic! change in government - Yes!! Then I went and looked up his record and what he stood for. That was the end of that.
