[However he is uncontaversial compared to Santorum. Also he has voted with NH's libertarian streak, For example he voted against some parts of the Patriot Act, He also not to mention voted to censure Gonzales. His record his actually quite moderate.
He's definitely not "moderate". He's solidly conservative, but he'll show a little independence two or three times a year. I would agree that Santorum is much worse.
On the big issues, he is at odds with the vast majority of NH voters. The war, the minimum wage, stem cells, abortion, etc.
