Exactly. He stated throughout his career he wasn’t a Democrat. But, he was advised, that to have any chance of becoming President, he had to join the Democratic Party, first for the media coverage, and second for its money. He did it not because he had the convictions of a lifelong Democrat, but he did it for his own means. He’s being hypocritical and establishment Democrats get that. That’s why he loses in closed primaries where only registered Democrats can vote. One more reason why he is losing. And will lose. I think Donald Trump has the same problem. Trump really isn’t a conservative Republican. He’s just using the Party to run for President.
