I would even go so far as to say the party has abused and relied on the excuse "they're worse than we are" to the point of failure. Even the last few elections a popular stance is to go full reverse logic and let things burn down because the "better" side doesn't care about the people either vs. the position of power. And I'm finding it hard to argue against them.
Locally, get informed about real choices (hopefully) or even get those choices to run, and vote. That is what makes the difference for things that affect you directly. The national scene is all but a lost cause though. The ones who could start to fix the inherit problems within are the ones benefiting from the status quo.
