Chafee is the sort that would vote against Alito and vote against breaking a filibuster. Except, Laffey is running against him. So on one side he has a Rep challenge, the other side a Dem challenge. Chaffee isn't struggling over whether to vote for Alito. But whether to break the filibster as a result. Not that it matters at this point.
chafee has said he won't filibuster
but chafee will vote against him, that vote is meaningless
but chafee would not vote for the nuclear option if the dems do filibuster
