Washington, Nov. 3: With less than 48 hours to go for Election Day, both John McCain and Barack Obama''s campaigns are trying to motivate voters to come out and vote on Tuesday.

According to FOX News, both camps are positioning themselves for a long night on Tuesday and do expect the closing stages of the race to be tight, as there is a potential for fraudulent voter registration.

The latest Investor''s Business Daily-TechnoMetrica poll out Sunday showed the race with just a 2-point spread, with Obama at 46.7 percent, McCain with 44.6 percent and 8.7 percent of the 844 likely voters still undecided.

McCain''s team points to several other polls showing the race tightening as the nation comes into the home stretch this election season.

His campaign manager, Rick Davis, told "FOX News Sunday" not to discount McCain, who was the underdog in the primaries and came roaring back.

"Look, this election is moving very quickly. There is no doubt that John McCain is increasing his margins in almost every state in the country right now. And I think that what we''re in for is a slam-bang finish. I mean, it''s going to be wild. I think that we are able to close this campaign," Davis said.

"John’s a closer, he always has been," former McCain rival and Tennessee Senator Fred Thompson said on NBC''s "Meet the Press."

"He''s been given up for dead -- literally and politically. People have been wrong about him before. He''s in his element now. And he''s feeling good about it. So, I would not count him out in any stretch of the imagination. I think the election is yet to be decided," he added.

As for the Obama camp, chief strategist David Axelrod told ABC''s "This Week" that the McCain camp is deluding itself into thinking he can stage an historic comeback.

Axelrod, however, said he is worried about potential new voters not going to the polls because they believe Obama has it wrapped up.

Campaign manager David Plouffe said the Obama team expects at least 130 million voters this election, particularly from states where Democratic registration has increased this year. Plouffe added that Obama is not running a national campaign, he''s focused only on
16 states.

"We think we have a decisive edge right now. So John McCain would have to win Election Day by a huge margin to make up those deficits," Plouffe told "FOX News Sunday."

Both sides are also talking about criticism about the voter registration process and how so many millions more people are on the rolls. Plouffe said that any fraud would be investigated, but obvious fraudulent registrants won''t make it into the booth. (ANI)
