A CNN/ORC national poll released Sunday showed President Obama and GOP challenger former Massachusetts Gov. Mitt Romney in a dead heat among likely voters. Forty-nine percent of likely voters say they are backing the president, and an equal amount say they are backing Romney.

Three other national polls have shown the race in a virtual tie among likely voters.

CNN’s final poll before the election showed a gender and age gap. While Obama managed a tie with Romney among senior citizens, he has lost some of the steam he had among young voters in 2008. Obama also leads Romney among women.

“Fifty-three percent of women say they plan to vote for President Obama compared to only 44 percent of men,” CNN Polling Director Keating Holland told CNN Sunday. “That works out to a nine-point gender gap, which would be the largest since 1996.”

Romney leads Obama 52 to 47 percent among voters making more than $50,000 per year. He also leads in the South, West and suburban rural areas.

Here are basic facts about each candidate before you head to the polls Tuesday:
