Here's something I think the vast majority of Republicans/conservatives/libertarians can agree on: holding Obama to this pledge, made to the American public during the third debate:

what I've done throughout this campaign is to propose a net spending cut.... What I want to emphasize ... is that I have been a strong proponent of pay-as- you-go. Every dollar that I've proposed, I've proposed an additional cut so that it matches.

UPDATE: Not that I expect this to happen, but it would be wonderful if Senate McCain and the Senate and House minority leaders each congratulated Obama, and added, "we look forward to helping President-elect Obama fulfill his promise of a net spending cut."

FURTHER UPDATE: More generally, and with Congressional Democrats eager to go on a spending binge that will make George W. Bush look like Calvin Coolidge, it's worth reminding whoever will listen that at least in the general election, Obama didn't run as a big-government liberal, but as a tax-cutting, spending cutting fiscal moderate-conservative. And no excuses, please, about the need to increase spending to deal with the financial crisis/looming recession, both of which were more than apparent by the third debate.
