That's certainly possible, but I think unlikey that Bush will win the popular vote. I'm actually hoping for an electorial college tie. 269-269. I'd love to watch Bush's fellow Texan Tom Delay preside over the victory as the new house members cast their vote for president.
Yeah, having Congress "appoint" the president is a great way to unify an already dangerously polarized nation.
Actually, the most disruptive thing that can happen is a close race, with many voting scandals in several states, numerous lawsuits, culminating in an "appointment" of Bush or Kerry weeks after the election. Not good for America, whatever the outcome.
