Bush, McConnell, Frist, Shellby, et.al. are liberals? The first three oversaw a near doubling of our debt and a tremendous increas in the size of government and the last is one of the biggest entitlement hogs going.
To not even acknowledge that the South is the most conservative part of the country is at best intellectually dishonest. However, I would give the Midwest/Inter-mountain West the #2 Ranking in that category. In fact, I once lived in the Inter-mountain West and the folks there did not care where you came from as long as it was NOT from the Northeast or California.
