I I agree with Matt that 1)it was stupid of Obama's campaign to pick a fight with Paul Krugman, but 2) Krugman's point is very misguided. I don't think that Obama's rhetoric about transcending old politics tells us much about how he'll actually govern. Bush in 2000, after all, didn't campaign as a 50%+1 conservative who would increase party polarization in Congress, but that's what he did. Obama's using this kind of rhetoric because 1)it's effective, and 2)he's very good at it. What actually matters, however, is the substance of his policies and record, and on that count he's clearly superior to Clinton (especially on foreign policy), although on domestic policy there's a strong case to be made for Edwards. I also second Matt's point about institutional realities; as nice as it would be if we would be inaugurating a Prime Minister in 2009, no major reform can be passed without the votes of some Republicans and conservative Democrats in the Senate. Given that she generates more hostility from the GOP (despite being more conservative), it seems very unlikely that Clinton is likely to get more accomplished if she's elected. --Scott Lemieux
