Jesus has always been fairly liberal and borderline to actually socialist. He literally said rich people are more likely to go to hell because they cause problems for the poor by not helping them, and told someone rich that it's not good enough to be a nice person, but to actually follow him, that he had to donate to charity.

He also hated and actively fought with organized religion, and especially profit-driven organized religion. People say stuff like "What would Jesus do." but he made himself a whip and used it to chase people out of a synagogue and flipped tables because they were trying to profit off of religion like they were an extortionate business.

Hell, even the messianic prophets like Isaiah are very socialist. I would honestly say that parties like one of the Christian Socialist parties would better fit his stated ideologies than any conservative party. People have the wrong view about Jesus because Republicans and similar parties misrepresenting him, but he HATED people like the Republicans and Mega-churches.

Jesus was all like, "Love you enemies and be kind to those who use you." but then turned around and said stuff like, "You brood of vipers, you are sons of your father the devil, and how can you be saved from the fires of hell?!" to the leaders of the church at the time. Which shows you how much he hated and was angry at them, that he didn't even try to reconcile with them, which is why they assassinated him later.

Note than I'm not Christian (anymore) but I spent a long time as one and I learned a lot, and the biggest think I learned is that Republicans are not only not Christian, they actively misrepresent Christ and everything Christianity is about.
