His record has been quite extremist. In many ways more logical than the current Bush insanity, but always pretty extreme. Ironically he has spent years trying to appear more moderate, now finding he has to come back home to the extreme right to pick up support. But his voting record shows:

consistently anti-choice and anti-women's rights,

consistent support for tax breaks for the wealthy,

largely consisntent anti-first and fourth amendment rights,

mostly loved by John Birch Society, the "Christian" Coalition and "Concerned" Women of America,

anti-alternative energy,

largely anti-union,

low ratings from AARP and DMI,

and an ironically low rating from most Veteran's groups ("D" rating from Iraq and Afghanistan Veterans of America, for example).

He seems more mixed on environmental issues.

By and large his votes line up solidly with the most reactionary of Republicans, though with some exceptions.
