Can we stop calling the US Senate a "deliberative body"

4. The filibustering would go away (or severely diminish)

if they had to get up on the floor and talk in order to maintain a filibuster. I'm o.k. with a filibuster provided that it isn't allowed to hold things up indefinitely. I sort of like proposals that make it so that it becomes harder and harder to sustain over a period of time- so that people have to do a little work to sustain one. This would allow the minority to slow down the process and potentially rally people to their side but would also (eventually) allow for a vote.
