Just for the record, I'm against attacking Iran
I think Congress needs to get out ahead of this, because there are all kinds of signs that this administration is gearing up for some sort of conflict with Iran. Of course, this administration is pretty contemptuous of Congress. So ultimately I think cutting off funds for any attack or Iran may be Congress' only choice. That or impeachment.
If this rumor about dumping Cheney is true, maybe that will help. Then maybe Joe Liberman can be vice-president. But then he's a deluded warmonger, too.
It's really hard to get around the fact that as far as foreign policy is concerned, we're pretty much fucked until we can replace the current administration. January 2009 is still two years away.
