I agree that the solution is for millennials to get more politically active. But the cards are sort of stacked against us. We have less money over all than prior generations which means any representative we want is likely going to be outspent by older representatives (for not being whiny or whatever).

On top of that, the political landscape has changed somewhat significantly. What changed is we have computers to draw congressional maps that remove political competition. There are few "swing" districts in the US and that has a lot to do with computer aided gerrymandering. That sort of system makes it easier for an old fart to stay in power for far too long, because they've picked constituency that won't remove them from office for bad behavior.

Of course, the only solution is to be less apathetic than the boomers and gen xers. To vote in very large numbers that are hard to ignore. That, however, is a hard thing to pull off. It's hard to convince people that their vote matters and will make a difference or that participation matters.
