I don't think anyone would propose that our democracy be replaced by another system. That being the case, the problem you cited so succinctly can only be resolved in one way...replace those in the Congress that we believe have mis-served us.

There's potential to make a huge change next year, when every single member of the House and 1/3 of the Senators must run for re-election. If we vote 96% of them back into office, as has been the pattern in the past, then we deserve whatever government that we get...and we'll have little to say about trusting them or even controlling what they do.
