WEST LEBANON - Republican presidential candidate Mitt Romney blasted U.S. President Barack Obama over the size of the national debt and the record number of Americans on food stamps, in a jab on the eve of a major speech by the Democrat.

Romney said "two big numbers out this week" prove that Americans are not better off than when Obama took office in 2009.

"We've gone from $10 trillion that the president inherited from all prior presidents to $16 trillion," Romney told reporters in the swing state of New Hampshire. The Treasury Department this week announced that the public debt had surpassed $16 trillion.

"The other number's forty-seven. Forty-seven million now on food stamps. When he came to office there were 32 million. He's added 15 million people," Romney said.
