Just implement Rule 19....limits discussion on the topic to two speeches for each Senator ,....and requires a 50% vote to pass when all Senators have had their two speeches.
seems to be effective since I seen or herd (no pun intended) neither hide nor hair of Poxahuntas since.
The 60 vote rule is unconstitutional in that it gives more power to the senate than was intended by the founders.
A federal judge can step in and prevent the president from doing this or that on constitutional grounds, so likewise, shouldn't a (special prosecutor) be able to prevent the senate leader from doing likewise?
