The system isn't broken due to filibuster - that's protecting the system from party pettiness when the American people aren't "sold" that one party is better than the other. In this community we can argue and build consensus - not everyone agrees with everything, but if you participate sometimes your mind can be changed. The challenge for Chuck should have been let's get work together, but no he spent years "aligning" people and probably promising them certain assignments, pork, and donations... so now he pays the price. And no, I do not believe Mitch is any better - I see them as glowing examples of your time has passed, let someone else lead. Still, like in baseball not everyone wants to lead the team, some just want to play the game, some are willing to be role players. Power is intoxicating and not everyone can control themselves once they have it.
In order to start to fix the problem I believe we have to get rid of lobbyists, have term limits, create an age peak (we have a floor), reduce the size of bills, remove pork, have a balanced budget amendment, don't allow large donors to manipulate things (there's examples on both sides), etc. etc. I disagree about the salary thing, but certainly understand where the thought comes from (I used to live in NH and my father was a state Rep for a few years). Anyone who was in an office collaborating for years and now has to be at home via video platform knows how hard that is, so governing completely remote is not an answer, but I see solid logic behind shorter sessions in Washington. Everyone knows nothing gets done until the deadline anyway ;-)...
