Finally, the final day of campaigning - KMSP-TV

Years of campaigning and billions of dollars of advertising comes down to today, the final day for the president and Mitt Romney to try and rally supporters and motivate the remaining undecided voters.

The candidates going to be incredibly busy, holding nothing back. The president will spend Monday in Wisconsin, Ohio and Iowa. Romney will hit Florida, Virginia, Ohio and New Hampshire.

Ohio is so important Vice President Joe Biden spent all of Sunday there at three rallies.

"Character is the single most important ingredient a president must possess to lead this great country and to lead the world," Biden said. "Quite frankly, it's clear who has character and who doesn't have character."

Republican vice presidential candidate Paul Ryan stopped by the Minneapolis airport Sunday afternoon.

"We know we can't keep going down this path," Ryan said. "We can't accept four more years like the last four years."

In addition to rallying supporters in Ohio and Colorado, President Obama was also in Ohio and Colorado, in addition to Florida and New Hampshire.

Mitt Romney hit four states as well: Ohio, Iowa, Pennsylvania and Virginia. They all did their best to energize their bases and reach-out to those who haven't quite made up their minds.

"I want to stop giving tax breaks that reward companies that are shipping jobs overseas," Obama said at a Colorado rally. "Reward companies that are investing here in America, in the next generation of manufacturing. That's how we grow an economy. That's how we create jobs."

"The same course we've been on is not going to lead to a better destination," Romney said at a Virginia campaign stop. "The same path means $20 trillion in debt passed on to our kids. It means crippling unemployment and stagnant take-home pay and depressed home values and it means a devastated military which we must not allow to have happen."

Most polls show the race is still too close to call, with a possible slight Electoral College edge to President Obama. That's why the voter turnout efforts are so huge right now -- because just a few thousand votes in each swing state, in either direction, could decide who's inaugurated in January.
