The Supreme Court has consistently held that except for the supermajority votes required by the Constitution (treaties, veto override, constitutional amendments), all other votes require only a simple majority.
The Constitution does not specify a supermajority for presidential nominations.
The current Senate rule, which effectively requires a supermajority for nominations is, therefore, on its face, unconstitutional.
I've never been in favor of filibustering judicial nominees. As such, I don't oppose what Reid did today....
Please stop assuming everyone is as a big a hypocrite as you.
