If they had REAL guts, they’d simply have a roll call and vote NO on every nominee Obama sends.
They would absolutely be fulfilling their Constitutional duty in doing so.
If they put off a vote, the democrats and press will attack and hound them every day.
Will the Pubbies have the guts to pull a Bork on the next Obama appointee - I’m not so sure. However, if they don’t I see a potential pitchfork uprising by a lot of us out in the fields.
From what I’ve heard on TV, there is a precedent for not approving a SCOTUS appointee of a Lame Duck Prez (IIRC about 80 years). Also, there is nothing written about the number on the SCOTUS, so if we have 8 rather than 9, perhaps not an issue from that perspective, but could mean tied votes or worse for upcoming cases like immigration, Little Sisters of the Poor, etc.
Don’t worry, McCain will come to Obama’s rescue and pronounce Obama’s SCOTUS pick as fair and just.
From your lips to God’s ears. Run out the clock.
