I see a lot of posts regarding Jesus being Jewish and therefore being liberal, but wasn't he condemed by the Jewish priests for causing trouble. Instead of looking at only whether or not him being Jewish would affect his political leanings, lets look at his actual teachings and ideas.
He said to turn the other cheek and forgive anyone that does something bad to you. I don't want to pigeon hole an entire political ideology but on the highway, it's never the person in the Prius honking and flipping you off; it's the guy in the big truck with a confederate flag and gun rack that does.
Jesus spoke a lot about rich men and helping the poor. The liberal philosophy has a lot more programs and policies geared towards helping the poor then the conservatives do. While both sides of the political spectrum have wealthy members, the conservative ones seem to be much more worried about letting go of theirs.
There are many other examples, some that show Jesus to be a conservative such as being against government establishment, but overall I think that he would be considered liberal today.
