A new national poll is showing a dead heat in the presidential contest, making this an opportune time to revisit the question of whether the Nov. 6 election might produce a 269-269 electoral vote tie.
The prospect of an electoral deadlock has been around for months. It was explored here over the summer, with an explanation of why a tie would likely result in Mitt Romney becoming president.
Intrade, the online prediction market, currently pegs the chances of an electoral-college tie at 5% (down from a peak of 10% earlier this month). Heading into the final two weeks of the campaign, Romney and President Obama were at 47% each in the latest NBC/Wall Street Journal poll, released Sunday night.
Of course, the White House is won in 51 separate elections, not by the national popular vote. And at this point, the outcome in 42 states and the District of Columbia seems to be pretty much locked in. That leaves just eight tossup states, where neither man has opened up a lead greater than 3 percentage points in the latest RealClearPolitics polling averages, to decide the election.
