He's deciding whether to join the parade after the street sweeper has passed by. I would almost rather have Flake vote no to keep it 50-50 to keep the red state Dems away.
Manchin has to vote yes to get re-elected. What Manchin needed was for Kavanaugh to withdraw from consideration. If the deocrats have any brains, they will keep pounding Flake, Collins, Murkowski. They need these rino senators to vote no, so that Manchin could vote yes without being the 50th vote.
