Bloomberg is just another leftist in Republican clothing, a real Bush Crime Family hooligan.
He only ran for Mayor of New York as a Republican because after Rudy, and 9/11, no Democrat would be elected Mayor of that City. He remained a Republican until 2007, then changed to Independent and got a special third term from the City Council. In 2018, he went back to the RAT party so he could run for President as the life-long RAT he was.
