The Democratic party is certainly more liberal than the Republican party, but I personally think that is because the Republican party has become so much more conservative in the past few years. As an example, I read a Gallup poll that said the majority of Republicans in the United States do not believe the theory of evolution is true and do not believe that humans evolved over millions of years from less advanced forms of life. That just shocks me - it goes against every scientific principle we've ever been taught. I guess, in addition to being conservative, republicanism is also anti-intellectual.
