He occasionally hinted at the need to vote for more Democrats, but I don't recall a single case where he actually SAID that. Instead he said things like "Obstruction isn't governing." "We need to work together better." "We have a poison atmosphere."
What he didn't say is "Ladies and gentlemen, the Republicans have vowed they will oppose EVERYTHING. The only way we can move forward is to vote for people who aren't going to obstruct, and at this point that means the only real solution is to vote for democrats." or anything remotely similar to that.
He was nowhere to be found throughout the crucial Wisconsin battles. He is simply out for himself -- no way around that.
