Unfortunately I was on the road, and didn't catch the debates. But from what I've seen on TV, Kerry seemed to do very well.
As far as other points. Kerry can change Iraq to a point, by being likeable and respected by other nations that Bush has pissed off. Garnering that support can only help take the financial burden off our shoulders. No matter what, people in general, no matter what the party need to realize that democracy will never work in that country or many others in the Middle East for that matter.
I think the N. Korea thing is that there are people out there that feel China is screwing up the negotiations, basically because China's govt. may be as nuts as N. Korea. And no matter what, N. Korea is a place where we need to intervene, because it is proven that they have the WMDs.
And as far as taxes go...just pay them. The tax cuts do nothing. Yeah, they put some extra bucks in our pockets, but is that really needed against the common good. The deficit has gotten completely worse under Bush, and so had govt. funding of necessary programs because of the stinking tax cuts. People want all the shit the govt. does for free. Everyone needs to shut the fuck up and just pay the damn taxes!
