The alternative is a party only focused on making the rich richer and staying in power even if they have to kill democracy to do it. I’d take partial solutions or failed attempts at doing the right thing every time over that. We don’t have other realistic options. From time to time we get populists who are mostly talk.
The word corruption gets thrown out far too much too. Those that break the law should be punished, but simply adding something to a bill to benefit your constituency is literally the job, and far too often I hear people say that’s corruption. It’s compromise.
