The time voting would help was gone years and years ago. If you want to make peaceful change now you're going to need to get involved in politics directly (e.g. "The pirate party" but don't call your party that in the US. In fact, I'd call them "democrats" or "republicans", which ever is more popular). Until enough of us do this, things will just continue to get worse. There is no politician out there who truly has your interests at heart. Even if there is, they're alone (e.g. Ron Paul and I don't even agree with the majority of his platform).
