NATIONWIDE -- President Barack Obama and Republican presidential candidate Mitt Romney will be campaigning today in five swing states.

Romney heads to Ohio as he concludes his multi-state bus tour. He campaigned in Florida for Senator Marco Rubio, explaining why he picked Wisconsin Congressman Paul Ryan as his running mate.

Romney said, "I think that we recognize people based upon their values and their capacity to get America on track, and I picked the person who I believe is the right individual to help me, if I become president, to be able to get America to finally be able to work together in Washington, Republicans and Democrats, to solve the extraordinary problems we have."

Ryan will make stops in both Colorado and Nevada today.

Meanwhile, President Obama is on the second day of a bus tour in Iowa. He spent Monday talking to farmers and discussing Paul Ryan's economic policy. Ryan was also in Iowa Monday.

In 2008, Obama won Iowa with 54-percent of the vote there.
