Yup. As you and others have pointed out here, there were ample opportunities for Fetterman to make pointed, valid statements.There isn't a winnable stance on the supreme court other than "Vote for me and we can sign things into law to secure basic human rights. Voting for me also gives you a voice in votes for or against supreme court justices. A vote for me is a vote for the power to appoint.". That's the Republican messaging. Use that.
It seems to me that he didn't have anyone properly prep him for the debate. "Processing" problems aside, someone should have drilled into him such pre-programmed responses. Huge opportunities missed here.
Other than that, Fetterman should simply have refused to debate. Why do we "liberals" lack the rock solid confidence of right wing candidates, who never feel the need to apologize or explain ANYTHING?
