President Obama and Secretary of State Hillary Clinton are among the politicians whose past criticisms of the Electoral College system would draw new scrutiny if there is a split verdict in this year’s presidential election.

National and swing state polls suggest it’s possible Republican Mitt Romney could win this year’s popular vote while Obama triumphs in the Electoral College — potentially marking the second time the rare split in outcomes has occurred in the last 12 years.

The last time it happened was in 2000, when Democratic candidate Al Gore won the popular vote but lost where it mattered. George W. Bush won Florida’s disputed recount, propelling him to 271 electoral votes — one more than he needed to take the White House.
