There's 3 quit so far, more are expected to follow, and could you imagine the outcry if Trump sent out feelers to get support for something from the Democrats as his own side would likely reject it? That's what's happening in the UK now, the "Government" is having to beg to the opposition for help because they know their own people will tell them to do one.
Oh, and your description of Trump is actually a perfect description of the UK Labour party, Again, they make your lot look like amateurs thanks to their casual sexism and racism (the second you state candidates can only be a specific gender and/or racial ethnicity is the second you show your own sexism and racism, for you are deliberately practising racial and/or sexual prejudice no matter what you think you are doing) and their institutionalised anti-semitism. And all you have to do then is be a "human rights campaigner" who writes a so-called "independent" whitewash, erm, report saying that there's no such thing, even though your own party disagrees, and you quickly get a seat in the House of Lords where you can cream off thousands a month for not even turning up.
As I say, you guys have a lot to learn.
