He completely capitulated to the system for money and power. Look at where his donations came from. He never sought for major change or showed much effort to change the status quo of his own party. He constantly tried to stay in the mainstream. He felt going outside the mainstream wasn’t pragmatic, hence it took him until 2012 to stop “evolving” on gay marriage and come out in favor of it. Say what you want about Trump, but one thing he did, was he was willing to go after members of his own party (not the swamp part, just those critical of him). Now, only a small percentage of anti-Trumpers remain. Obama did nothing to remake the party in a new image, he was basically a third & fourth term of Bill Clinton.
