Another poll, another sign that the race between President Obama and Mitt Romney is too close to call.
An NBC News/Wall Street Journal survey released today shows the two candidates tied at 47%, with little more than two weeks to go until Election Day.
The last NBC/WSJ poll, conducted before the first presidential debate, had given Obama a three-point lead, 49%-46%.
Also note that, in the new poll, Obama leads Romney among all registered voters by five points, 49%-44% -- numbers that reflect Democratic concern that their voters aren't as enthusiastic as Republican voters.
A variety of polls show a tight race, well within the margins of error. The Real Clear Politics website, which averages all surveys, also has the Obama-Romney tied -- also at 47% each.
In addition, Real Clear Politics forecasts a down-to-the-wire, state-by-state battle for the Electoral College, which will decide who wins the presidency.
The two candidates have their third and final debate -- this one devoted to foreign affairs -- on Monday night in Boca Raton, Fla.
NBC News also reported on its new poll: "Looking at some of the most important demographic groups, Romney leads among men (53 percent to 43 percent), Obama is up with women (51 percent to 43 percent) and they are essentially tied among voters in the Midwest."
