Which party is more corrupt? According to a blog posted on American Thinker, Democrats are 4 times (or 300%) more corrupt than Republicans. The blog relies on data from the National Taxpayers Union compiling convictions of major offenses by members of Congress from 1992-1999.
On the other hand (the one on the left) CREW lists the 20 most corrupt members of Congress and has the Republicans leading 13 to 7. No matter what your party affiliation, your bleeding heart or conservative principles are bound to be broken by a politician at some point.
