- No term limits in Congress, so people have a huge edge as incumbents
- It’s very hard to primary someone and defeat the current person in your own party.
- There are only two parties which have an impact, which means you end up voting for “one of two.” And when neither are great options, neither will turn out to be great options.
Essentially, the number of times you can make a choice is very limited. (Basically to when someone resigns or steps down or runs against the opposite party.) and then when you have a choice, you don’t have very many compelling alternatives.
Are you really hoping that you can convince enough people to abstain that eventually the two major parties will have an epiphany and feel so ashamed that they'll fix the voting system to allow more competition and better representation?
I think you really need to consider who you are up against here, which is people who are prepared to fight dirty for unchecked and undeserved power, who will treat your abstention as being consent for their misrule.
