It helps to remember that life itself has checks and balances on evil people -- even if our Constitution doesn't.
Life, thank God, is infinitely more complicated than politics. That's why politics is such a joke. That's why this "Democratic Congress" is a sneeze in a hurricane. Larger forces are at work.
The BIGGEST untapped into force isn't a pretty thing to talk about, but it may turn out to be our salvation and this is the force of raw self interest.
Bush Democrats are so far beneath contempt they don't even show up on the moral radar, but they all have an Achilles’ heel and that heel is their predictable, slavering self interest.
The Judas Joe Lieberman's and DLC Hillary Clinton Doll’s (machined by James Carville) would clearly do ANYTHING if they thought they could get away with it, and yet they won't allow themselves to get SO greedy and dishonorable that they call counter productive attention to themselves.
To say it straight out, evil people typically don't publicly kill other people to further their self interest; however, this isn’t because of "conscience", it’s became they know public murder would almost certainly counter their own selfish agendas.
In short, evil people (e.g., Bush Democrats) are not "conscience people", they are "self interest" people and this is a kind of Achilles’ heel, because this is where their true vulnerability and craziness lies. Thus, the strategies we need should have nothing to do with ethics, law, and rationality, because pig people don't even know how to spell such words (listen to Bush talk about science!).
No, the only way to deal with truly evil people is to discover their secret self interests and vulnerabilities, because this is where our leverage is.
