It's pretty unlikely the democrats were unaware and they should be held accountable as well. After all, do they care about kids or do they care more about making it an election issue?
The democrats want to make this a Republican vs. democrat issue and say the GOP didn't do enough. But if Foley broke Congressional ethics rules, then they all didn't do enough, democrats included. The democrats were too busy with their daily psycho-rants against Bush. Or maybe they knew about it for a long time and saved it up for the election. Either way, the democrats failed in their duty too. No, I don't buy it that the democrats didn't know.
