Both candidates vowed to bring about change in op-eds published Monday in The Wall Street Journal.

"After the difficulties of the last eight years, Americans are hungry for change and they deserve it. My career has been dedicated to the security and prosperity of America and that of every nation that seeks to live in freedom. It's time to get our country, and our world, back on track," McCain wrote.

Obama said that with him, voters can choose "the promise of change over the power of the status quo."

"So tomorrow, I ask you to write our nation's next great chapter. I ask you to believe -- not just in my ability to bring about change, but in yours. ... If you give me your vote, we won't just win this election -- together, we will change this country and change the world," he wrote.

McCain traveled from Florida, Tennessee, Pennsylvania, Indiana, New Mexico to Nevada in the day.

He was set to end the day in Prescott, Arizona.

Obama's final day takes him to three Southern states that voted for Bush.

In addition to Florida, Obama also held events in North Carolina, and Virginia.
