This would be the perfect opportunity. The Democrats voted for this cockamamie scheme to have a majority vote to disapprove the agreement, which Obama can then veto, to circumvent the Constitutional requirement of a supermajority (two-thirds) of the Senate to approve a treaty.
Now that they have their scheme in place they refuse to allow a vote. At the very least, McConnell should invoke the Reid Rule on this vote.
Alternatively, McConnell should simply say “fine we won’t vote on this scheme, instead we will submit it for approval as a treaty,” which will fail unless it gets a supermajority vote.
