I think that Dan Savage (of Savage Love, not to be confused w/ Michael Savage) has the best commentary on the Foley scandal, so I won't say much.
It isn't that he (Foley) is gay, or that he is a pedophile, or that he did anything illegal. It is simply that, because he is a Republican, everything is getting downplayed. Clinton got a consentual hummer from a leagal (of age) woman. It was stupid, immoral, deceitful, whatever other things you want to call it. It stalled congress, days of testimony, senators and representatives stood on their soapboxes to decry the moral depravity of the President. There was an impeachment. With Foley we get told they were inappropriate e-mails and let's move on. I got no love for many Republicans' draconian notions of sex, but I can deal with it if they have the character to be honest and consistent. They have not. The hypocrytical behavior that they exhibit is beyond immoral. This is why they have to go. It isn't that there are no good Republicans, it's just that they are not running the show in DC. Party does not come before country, state or district. Ever.
