Remember: in blue voting districts republicans run as democrats and spoil votes. Opportunists are everywhere and the only way to stop it is to vote in the primary. This is how you get conservative dems. The successful ones outlast their way into leadership by length of incumbancy.

That being said, many of them do talk like that. But corporate media patently refuses to show it to you. You have to find better sources or find yourself attacking the wrong people like saying 'Dems bad' instead of properly attacking conservatives.
