WASHINGTON, July 25 (UPI) -- Negative presidential campaigning is pushing more U.S. voters into polarized camps, with undecided Americans shrinking in number, a bipartisan poll indicates.
Both President Barack Obama and his presumed Republican presidential nominee Mitt Romney had the highest numbers yet of who viewed the candidates "very negatively," a Wall Street Journal/NBC News poll found. More than 40 percent said their feelings about the candidates had soured because of the aggressive attack ads each side has released.
