Not going to sugarcoat it, it's bad, it's real fucking bad. But there's 2 options
Option 1: you just give up and let them win
Or
Option 2: you get pissed off, and do something about it, you organize and fight back via every legal avenue possible, you get people who can do better to run in every race you can, and you go out and vote every damn time and bring as many people to vote with you as you can, and maybe, just maybe, things get better.
Your vote isn't always going to make a difference, but your lack of voting and giving up just lets people who want to ruin everything we have built take over, and guess what...they never fail to vote and fight for what they want.
The system sucks and gives shit people from shit states way more power and representation then they should have, but it's what we have and we need to make the most of it.
