Now that Fred Thompson is all but in the presidential race, it seems fair to start with his voting record, especially as it compares to the Republicans already running. The New York Times describes it as "decidedly but not exclusively conservative," which sounds about right.:
Pat Toomey, a former House member from Pennsylvania (1999-2005) who heads the Club for Growth, a fiscally conservative group that promotes free trade and cutting taxes and spending, offered general praise for Thompson's voting record. Toomey's group will soon issue a detailed “white paper” analyzing Thompson's record on economic issues, as it has done for McCain, Brownback, former New York City mayor Rudolph Giuliani and former Arkansas Gov. Mike Huckabee.
“As a general matter, I think Fred Thompson's career in the Senate demonstrates a guy who does have a pretty strong commitment to limited government, free enterprise and particularly federalist principles,” Toomey told CQPolitics.com.
