"Betting on America" preview

Here's what Obama is saying on the bus tour stump next door in Ohio, from David Jackson at USA Today:

In a campaign speech spiced with gambling metaphors, Obama said that "the stakes could not be bigger" in his race against Romney.

Democrats and Republicans are offering "two fundamentally different visions" about the direction of the country, Obama said.

Romney and other Republicans want to lavish tax cuts on the wealthy, Obama said, while his programs -- from education to health care -- are designed to help the middle class and poor.

Romney aides, meanwhile, said that unemployment remains over 8%, while Obama's spending policies have exploded the national debt.

"Four years ago, Vice President Biden came to Maumee to decry the national debt, which was then $8 trillion. Today, the Obama-Biden administration has presided over an unprecedented explosion in our national debt, which is now approaching $16 trillion," said Romney campaign spokeswoman Amanda Henneberg.
