Simply opinions - because things just don't add up. But that's politics. Everyone gets rich but the citizens, right?
There MUST be some pay off for her to support a NY progressive for president. Maybe someday - I hope before the election - we find out what it was she got in return for that short moment of support (and it will all be forgotten by tomorrow anyway. Younger voters don't even know who she is. John McCains wife maybe? LOL. )
I think her motivation is that she is sick of politicians and her pay-off will be seeing Trump elected.
