DES MOINES, Iowa, Dec. 30 (UPI) -- Republican presidential hopeful Mitt Romney, in recent campaign rallies and ads, calls U.S. President Barack Obama "pessimistic."
"We still believe in an America that brings out the best in all of us, that challenges each of us to be better and bigger than ourselves," Romney says in a television ad to be aired in New Hampshire and Boston. "It's time for this pessimistic president to step aside and let American optimism that built this greatest nation on Earth build a greater future for our children."
