Garland seems to me a sacrificial lamb. He is a known quantity so it will be hard for the Republicans to make him a pinata, like Cornyn promised to do to any Obama nominee.
And even if Clinton wins and they decide in November to confirm him I'm not so sure that people like Cruz and Mike Lee are going to be willing to go along.
But what is the alternative, should Clinton win and the GOP retain the Senate? The Republicans continue to block any SCOTUS nominations from Democratic presidents forever?
If Clinton wins then she will have a Democratic senate.
Any other combination is unlikely. Not to mention that the people would have spoken and any further obstruction will look like outright partisan spite even to the most casual voter.
