If you think McConnell has a monopoly on hypocrisy I have a bridge to sell you as well. McConnell took both sides of the argument (delay when convenient, expedite when convenient), the democrats opposed him on both occasions. If this was a moral discussion, then both parties are equally guilty of hypocrisy.
Now if you think that political appointments are a moral matter rather than a balance of power within the constitution matter, it's not a bridge that I have to sell you, it's a planet.
