It might be hard to believe after his assault on Mitt Romney in last night’s debate, but there’s a scenario under which Joe Biden could serve as Mitt Romney’s vice president.

As noted in an earlier post, there are plausible scenarios under which next month’s election could result in a 269–269 electoral vote tie, which would send the presidential election over to the House of Representatives. Such an outcome would favor Romney over President Obama, according to an analysis by the Washington Examiner.
