"I think the majority of Americans (including left-wing voters) have not fully grasped the fact that our standing in the world will not recover in our lifetimes.
Even if we elected two full-term Democrats in a row, it wouldn't change the perception of the rest of the world. Because the rest of the world has discovered we do not have a system that prevents our nation from pivoting 180ยบ toward authoritarianism when a madman is elected."

- Tony Rush

In the USA the best way is to write your representative and let them know if things don't change next time they are up for election they won't have your vote. I recommend snail mail and keep it professional. I'm skeptical about Emails and online polls and i've worked in tech for 30 years.

Writing your senator is not likely to have an impact in my opinion. Representatives are your neighbors and do actually care.
@hello ...I'm not a big believer on any of this having any impact on what's going on in the US...
