Nate Silver reports that the possibility of an electoral college tie is a real possibility if President Obama holds the states Sen. John Kerry won in 2004 along with winning New Mexico and Ohio in addition.

“The election would then be thrown to the House of Representatives,
which would cast votes based on the provisions of the 12th Amendment. Mitt
Romney would probably win such an election, because Republicans will
probably control a majority of state delegations in the incoming House
of Representatives.”
