Multiple polls show the race may be too close to call, with two polls giving an edge to Romney. The battleground states will play a pivotal role on Tuesday.
WASHINGTON - On the night before Election Day, Republican challenger Mitt Romney holds a slight edge in two national polls.
In Gallup’s final election survey, Romney came in with 49 percent to President Barak Obama’s 48 percent. After removing the 3 percent of undecided voters from the results and allocating their support proportionally to the two major candidates, Gallup's final allocated estimate of the race is 50 percent for Romney and 49 percent for Obama.
According to the poll, Romney holds a 10-percentage point lead among men -- 53 percent to 43 percent -- while Obama holds a similar lead among women -- 52 percent to 44 percent.
Another poll released Monday, the Rasmussen Reports, also finds Romney edging ahead with 49 percent of the vote while Obama earned 48 percent. Its Electoral College projection showed the president with 237 Electoral votes and Romney with 206. Eight states with a combined 95 votes Rassmussen projected as a toss-up. A total of 270 votes are needed to win the White House.
But not all polls favored the challenger.
Incumbent Obama held a 2 percentage point lead over Romney in the Reuters/Ipsos daily tracking poll.
Of 4,725 likely voters polled nationally, 48 percent said they supported Democrat Obama and 46 percent said they backed Romney, a former Massachusetts governor, according to the poll.
Obama and Romney made their final urgent pleas to voters on Monday in a closing sprint through vital battleground states, hoping to whip up strong turnout from supporters and to sway the few remaining undecided voters in the last hours of the race.
Four of those swing states may tip the outcome of Tuesday's election, according to another Reuters/Ipsos poll.
Obama maintained a 4 percentage point lead in Ohio, and slimmer leads in Virginia and Colorado, while Romney led by 1 percentage point in Florida, the poll showed.
In perhaps the most pivotal state of Ohio, Obama had the support of 50 percent of likely voters, while Romney was at 46 percent. On Sunday, Obama led 48 percent to 44 percent.
In Virginia, Obama held a slim lead of 48 percent to Romney's 46 percent among likely voters.
In Colorado, Obama was also at 48 percent, a nose ahead of Romney's 47 percent.
Romney had a slight lead in Florida, where 48 percent of likely voters sided with the Republican and 47 percent backed the Democrat Obama.
