Washington Post: Obama Has 'Slight Lead' in Electoral Votes

While the popular vote may be a toss up heading into Tuesday's election, President Barack Obama has a slight edge in the all-important electoral vote count needed to secure the presidency.

The Washington Post reports on Sunday that the "biggest and most consequential unknowns" focuses on voter turnout and the make-up of the electorate.

"An electorate that resembles or even slightly exceeds 2008 in terms of the share of minority voters vs. white voters would clearly benefit Obama," the Post reported. "A slight decline in the minority share of the electorate and a more even split between Democrats and Republicans — closer to the 2004 electorate than 2008 — would greatly help Romney. Obama, however, may do better among white voters in some of the battleground states than he will do nationally."

With 270 electoral votes needed to win the White House, Real Clear Politics showed President Obama leading with 201 electoral votes compared to 191 for GOP presidential nominee Mitt Romney on Sunday.

Real Clear Politics reports that 146 electoral votes are still up for grabs.
