Will add they should expand Congress. Right now each one reps about 800,000 citizens where the western world average is closer to the 100,000 range. So build a new building, limit it to say the 200,000 range and watch as regional/third parties become viable.
Won't do that much for third parties at the national stage, but
may help with regional parties. Getting some consistent congressional reps in just because there are more opportunities might give them a bit more time to build real party infrastructure.
That aside, expanding Congress is LONG overdue.
One for every 200,000 would put the US somewhere around 1800 reps if we go by anticipated 2030 population. (Since this obviously won't happen overnight.)
For comparison, the Cube root law as an approach would get you to 711 (or 708 if you use the slightly refined formula).
The Wyoming rule would get you to about 602.
(Least variation would get you to about 1,000)
You could also do the implication of the original proposed growth pattern of the house from the original first amendment, but that math gets you back to 1 per 200,000.
I am dubious that most people would go for a 400% increase in the House, but I wouldn't really oppose it. (Especially given how much could be done virtually.)
Regardless, it definitely needs to be expanded.
(The Senate should probably be abolished or wildly reformed, but that's a LOT harder.)
Individual Campaigns cost less. Gerrymandering isn't nearly a thing because the bases are much smaller. Corruption becomes much more difficult. Citizens can actually reach there reps. Add the term limits and you will see a change for better, less corrupt governance.
Term limits will likely produce *more* corruption, though. Maybe with some very strict lobbying controls it might work out.
Smaller constituencies would have several advantages, I agree.
Of course, I'd like to see Multi-member districts as well, so that would be a bit of a trade off.
And kill primaries. They are a fake tool to perpetuate a two party system. Let parties just pick their candidates and then run them on their policy.
Primaries have nothing in particular to do with perpetuating a two-party system. Most countries don't have the weird, convoluted formal primary system the US has, but they end up with dominant parties anyway.
That said, I'm fine with them going by the wayside. Get the state apparatus out of them and if individual parties want to run primaries as broad general elections they can pay for and organize them on their own.
