Republican presidential nominee Mitt Romney's running mate Rep. Paul Ryan campaigned on Sunday in his own home state of Wisconsin, and must-win Ohio and Minnesota, highlighting his regional roots and blaming President Barack Obama's economic policies.

"This is the longest stretch I've gone without hunting since I think I was 12 years old," CBS News quoted Ryan as remarking to a fan at the tailgate for the Green Bay Packers game outside the Sideline Sports Bar and Restaurant near Lambeau Field in Wisconsin on Sunday morning. "Just a reminder that I'll be in the woods pretty soon," added the chair of the House Budget Committee.

Ryan, a Janesville, Wis., congressman, was joined by his family, including his sons Josh and Matt, as well as the state's top GOP officials, in Green Bay, Wis. more >>

Several recent polls show President Barack Obama with a slight lead, but within the margin of error, in the weekend before election Tuesday. Republican challenger Mitt Romney leads, though, among those who are most engaged and most likely to vote.

There have been three polls conducted through Saturday.

Pew Research Center shows Obama leading by three percentage points, 50 to 47 percent. The poll of 2,709 likely voters was conducted Wednesday through Saturday. The margin of error is 2.2 percentage points. more >>

With the presidential race about even, arguments can be made in favor of either President Barack Obama or Mitt Romney winning. Here are the reasons each side says their candidate will win.

3 Reasons Obama Will Win

It has always been about image for our current president. He rode a wave of euphoria into office four years ago as a "Celebrity-in-Chief." The media and Hollywood have spent much time drooling over him. And this guy is now a pro at soaking up the adulation. Therefore, when he was invited by Gov. Chris Christie to tour storm damage in New Jersey after Hurricane Sandy....well, it was a no-brainer. It would provide a measure of much-needed relief from the momentum which Mitt Romney had generated since their first presidential debate a month ago.

Whenever the president's glamorous smile breaks forth, I have to remind myself that I am not looking at Denzel Washington. Barack Obama knows how to play for the camera, in spite of his rather angry and grumpy performances in the debates. When he is not forced to discuss substantive issues with a conservative, he seems to know how to whip out the charm and play his celebrity role quite well. His all-star status among the elites is built around his persona....not around any real results during the past four years.

In addition to the elites, the many others who are swayed by this White House celebrity are generally people who don't realize the true financial and social implications of the Obama presidency. These "groupie-like" followers seem to be in a trance when they fantasize about this man. It is almost identical to the way people gawk over Hollywood celebrities. The less the public knows about the personal views of movie stars, the more the average American tends to be drawn to their performances on the big screen. That is the way many Americans like it. more >>

At least 28 newspapers that endorsed then Sen. Barack Obama in 2008 have switched over this year and endorsed Republican nominee Mitt Romney for president.

As of Friday afternoon, over 100 editorial boards of newspapers had endorsed Romney while Obama had received around 85. Several more will be making endorsements this weekend. Yet the two questions people from analyzers to voters are asking is why did those who endorsed Obama four years ago switch to Romney this year, and will they in turn convince voters with their endorsement?

Of the many reasons newspapers gave when they endorsed a candidate this year, most came down to the one issue that seems to be driving this election: the economy. more >>

New Jersey Gov. Chris Christie was Mitt Romney's first choice for the Republican ticket but the GOP nominee switched to Paul Ryan in a span of about two weeks, according to a detailed account provided by campaign insiders.

The campaign's top advisers at the Boston headquarters thought in late July that Gov. Christie had been offered the job, and the campaign had even made tentative plans to make an announcement before Romney's trip to the London Olympics and other nations, Politico quoted anonymous campaign insiders as saying.

However, shortly before leaving for the Olympics, Romney "paused" the decision. The day after returning from his overseas trip, the Republican candidate settled on Ryan and formally offered him the job within a week. more >>
