All you do by consistently voting the “lesser of two evils” is kicking the hangover down the road by keeping to drink more alcohol. You know every time that it will get worse and the sooner you get through the hangover, the sooner you could actually move on, but in fear of the hangover you grab the bottler another time.

With the measures you mentioned the problem is in particular that the current Democrats are not caring about them. They assume they will get the votes nonetheless and if they don’t it is fine because the Republicans will cover most of the donors interests anyways. Making noise only works, if it is followed by consequences. Leaving political violence aside, the only consequence a normal person can realize is not giving the vote if they aren’t heard.
