Those discussions are happening in some places, but there doesn't seem to be as much here. There are people going for lower state positions, attempts and petitions for getting ranked choice voting, and people trying to challenge from the left in Dem primaries. Which all does have to do with voting, but has the potential to pull Dems more left. People do reach out to their reps, but between money and team sports I'm not sure how effective that is.
The current system and environment is very much built to allow two parties to keep fighting while ignoring third parties, and getting out of that within the confines of the system is a slow process. Slow processes also suffer from people's impatience, often not changing things fast enough and losing support.
