I haven't seen any poll numbers yet. We probably won't know until election day. But Bush's DUI, and his poor reaction to the revelation, depressed his turnout in 2000. Knowing the Republican base, which is disproportionately Christian, they don't take kindly to their leaders trolling for teens.
History tells me that this will matter in a significant way. The only question is how much.
Then "they" need to get a clue. Foley never was my leader (or a leader of the vast majority of Americans). He represented one district in Florida. He no longer represents even them.
It's stupid to extend the blame to Hastert when he probably knew far less about the problem than did several Democratic leaders.
If voters are really going to choose which party to vote for, based on concerns about Congresscritters "trolling for teens", they need to seriously ask themselves which party likely has more Representatives engaging in this kind of behavior.
After 9-11, if any "Christian" tosses the election to the liberals, they can just pitch their bibles and start reading comic books for all the good they think their doing.
