Does it requires 50 votes, or a majority of the senators present and voting? And since the Dems would be the ones challenging the ruling, wouldn't they have to come up with a majority, not the Republicans?

You've got me, I really don't know. I think Senate rules votes requires 50% plus 1 of the entire Senate, but I really don't know.

And your other point is correct, Cheney's vote would stand unless the Democrats can get the votes to override it. Since Cheney isn't going to break a tie against his own ruling, the Dems would have to come up with 51 votes.

The big part is for the GOP Senate caucus to be willing to piss over the Democrats to no end.
