The die is likely already cast. Even a fake dust-up over john Kerry's typically obscure remarks is unlikely to make a difference.
The House seems in the bag at this point. As for the Senate, it seems that it's coming down to 3 races: Virginia, Tennessee and Missouri (Webb, Ford and McCaskell). We would need to get all three to win, barring an unforeseen upset elsewhere.
Even so, no doubt a Dem victory in the House will allow conservatives a wonderful opportunity to re-load. For the last six years, everything bad has been more or less Bill and/or Hillary Clinton's fault: 9/11, recession, stock market crash, poor job growth, the coddling of North Korea, Iran and Iraq, global warming, etc. But starting next Wednesday, everything can be the fault of Speaker Pelosi and the Obstructionist House.
So, we'll have all new vitriol and all-new hyperbole. Let's remember, even if we get the White House and the Senate in 08, these clowns will continue to bitch and moan that everything we are and everything we do is wrong, un-American, etc. They did that when they were the kooky John Birchers, and they'll do that long after George W. Bush has been unanamously elected Worst President Ever. It's what they do. It's our challenge to ignore them and marginalize their impact as much as we can.
P.S. This November 7th, lucky residents of SC's 5th Senate District get the honor of casting their votes for the estimable Frank Eppes. Those lucky dogs!
