Is there anything they can do that will actually do anything? Since saying stern things and asking for resignations means very little as recent history has shown us, what can you suggest that would be consequences? I remember a 'true progressive' being bandied about a few months ago that had abortion issues as well, so that's clearly not grounds for an ethics investigation or taking the seat away legally. As far as I know all they can do is wait for the people to support a new candidate for his seat when it's time to vote, since the republicans aren't about to censure/scold a dem working with them without a good reason. That would mean it's up to everyone who disagrees with him to find, support, and FUND someone to replace him, so I say that anyone posting here about how bad he is put their money where their mouth is and do something about it since that's the only consequences that seem to matter in these cases.
