You would describe this as being different from competitive?

I doubt any amount of money would matter if we had 1 representative per 30k people as written in the constitution, NY State is about 20 M people so you'd need to bribe ~300 of the ~600 representatives in order to get your way (and also do that for every other state).

yes, is there any evidence purple districts represent their constituents better? whats the different between being primaried in a 90% red district and running against someone of a different party in a swing district?
