Why would they vote to advance, yet not vote for her in the final vote?
This vote was to end debate (cloture). Prior to 2013, it would have required 60 votes to accomplish.

To make themselves look good, hoping no one will notice when they vote against her.
They aren’t going to block her from getting her up or down vote even though they will vote to block her confirmation.
That’s good enough, though, to get her confirmed even though they are going to ultimately vote against her.
But publicly, they say they feel the nominee deserves an up or down vote on the floor of the Senate even if they are going to vote against the nominee.
