Actually, the Left sacrifices its own almost every time, and typically in greater numbers than it's opposition. Not always, but majority of the time.

I know this because I was a Left Democrat until Bernis Sanders told me to vote for Clinton. He revealed the entire game when he did that.

So I 'Left' the party. Did't even look over my shoulder while leaving. They let us down with decades of lies upon lies.

And until this country has its revolt against this feckless government, the embarrassment and theft will continue, and get more brazen.
