I have to disagree. The Constitution mandates certain votes that must be carried by more than a simple majority, impeachment and treaty ratification being such examples. However, the vote for confirmations is not mentioned. Therefore, the logical implication is that such votes require only a simple majority.

While you are right that the Senate can make its own rules, it cannot make rules in contravention to the Constitution.

Who are you, Harry Blackmun's ghost?

I don't care about emanations, penumbras OR "implications".

There is no textual support for the proposition that the Senate must DO anything, or NOT do anything, in ascertaining whether or not it consents to a President's nomination.

What constitutes consent is entirely up to the Senate.
