Congress needs to be expanded to do its job, and drop the filibuster. We need more, proportionally allocated representatives. Representatives that come from more than one of two parties. Representatives that spend more time at home than on the campaign trail or in DC.
Representatives with term limits. It blows my mind that someone can be a career congressperson. It creates precisely the same adverse incentives as being a career president. Your whole focus becomes making sure you stay in power. Which for congresspeople means toeing the party line.
I think filibusters just need to go back to how they used to be. If you feel strongly about something you better be prepared to blab for hours on end, on your feet. If you can't physically do that... well, maybe that's a sign in and of itself.
All for reps expansion. Remember that we haven't expanded in nearly 100 years because "we were out of room in the building". Meanwhile we have 435 people representing 330 million people (average of 760k people per rep), when the population representation was roughly 250k/rep the last time it expanded.
We should have at least 1000 reps by these numbers.
