Kicking off an Ohio bus tour, Republican Mitt Romney said President Barack Obama is offering a "foreign" vision of government.
At an airport rally in Vandalia, Romney told several thousand cheering supporters that Obama believes bureaucrats in Washington, "know better than free people."
He also said that Obama will "weaken our economy and turn us into Greece."
Greece is trying to figure its way out of a severe financial crisis.
"If I'm President of the United States, correct that, when I am president of the United States, I will not cut our military budget or our commitment to keep America's military - second to none in the world," Romney said in his remarks.
Polls show Romney trailing in Ohio, which is critical to his hopes of becoming president. No Republican has won the White House without winning Ohio.
Romney's advisers insist the race there is still close.
Romney appeared Tuesday with running mate Paul Ryan.
On Wednesday, Romney has stops scheduled near Columbus and Cleveland, and in Toledo.
Obama is also back in Ohio on Wednesday with stops planned in Bowling Green and Kent.
