In CNN Op-eds, U.S. Presidential Candidates Describe Their Visions for America

Obama stresses importance of middle class, Romney highlights his economic recovery plan; both play up their willingness to work across party lines.

With only four days to go until presidential elections in the U.S., incumbent President Barack Obama and Republican hopeful Mitt Romney told the American people what their plans are for assuming the top position in the country - and why the other is unfit for the job -  In twin op-eds published on Friday.

"The petty differences that consume us in normal times quickly melt away. There are no Democrats or Republicans during a storm -- only fellow Americans. That's how we get through the most trying times: together," he wrote.

Recapping some of his achievements as president – including the wiping out of Osama bin Laden and the creation of more than 5 million new jobs in the last two and half years – Obama goes on to criticize Romney for adopting the same "policies that caused this mess in the first place," referring to the 2008 economic crisis, and asserting "the folks at the very top don't need another champion in Washington."

Romney's op-ed extoled America as the land of "freedom and opportunity," crediting the "hard work of the millions of Americans who built our remarkable experiment in self-government."  He blamed Obama for the economic slowdown and his "war on coal, disdain for oil, and his effort to crimp natural gas by federal regulation."

Romney promised to "champion small business, the great engine of job creation in our country, by reforming the tax code and updating and reshaping regulations that have suffocated economic growth." The former Senator also assured he will "roll back" on Obama's "arbitrary" military cuts and ensure the U.S. military remains strong enough to remain unchallenged.
