A 21st century Jesus would likely have been a prominent cheerleader of "Occupy Wall Street", with the modern-day bankers standing in for the moneylenders in Jerusalem.
He would be castigated by the Republicans and nationalist parties in Europe as a socialist-leftist rabble-rouser, and a supporter of uncontrolled immigration given his Parable of the Good Samaritan.
The right-wing media pundits would scrutinise his private life to find incriminating factors, likely condemning him for his association with "lowlifes", prostitutes and other disreputable types on the margins of the "great and good" in high finance and respectable society.
Since the historical Jesus was criticised for his habit of drinking wine and sharing table with discriminated members of society and flouting the conventions of the Pharisaic law, he would be depicted as an immoral "libertine" leading a lascivious lifestyle. Again, the media would go into apoplexy.
And since Jesus was critical in his time of the Roman patriarchal family, he would yet again be railed against by many conservatives for his "anti-family" stance.
I can't imagine many on the political right in America or the populist right in Europe liking him at all, really.
Not that he would seek political office, but he would never have a hope of getting elected if put forward. Too radical - especially with that idea of abandoning all private possessions and living in common.
