I have a strategy suggestion in this regard, Mark. The post-Watergate reforms occurred because so many new people, not beholden to the machines running either political party, were swept in. They caused the leadership absolute fits– and produced campaign finance and intelligence reform that endured.
I am only donating to incumbents who supported voting rights in 2000 and/or 2004. Most of my contributions go to challengers where the incumbent is a Republican. When I send in the contribution, I attach a note in Dutch uncle-ese saying that I expect them to support the right to vote.
If we can get a freshman class of 30 genuinely independent people who owe their victory to election reform activists, it could change the tone in Congress.
