From Crush the Street, by Brian LeDeay
Another option and the most likely it seems, is the “nuclear option”. This would involve Senate Majority leader Mitch McConnell changing the senate rules so that it would only take a simple majority to confirm a Supreme Court nominee. This was first done by the previous Majority Leader, Harry Reid (D) who changed the rules to allow all presidential nominations to be confirmed with a simple majority vote. The precedent is there, so there would be little political fallout from the move and McConnell has hinted that he would not hesitate to go nuclear if he had too.
While this move to filibuster by the Democrats is hardly surprising because of the intense pressure by their base to block anything that Trump has his hand in. They must consider though how much of an issue that they should make this. This doesn’t shift the balance of power in the supreme court, it will remain a right leaning court, and they are destined to lose this fight. It would make more sense for them to allow vulnerable Senators to vote to confirm Gorsuch and take that weapon away from the Republicans come election time.
