CINCINNATI (Reuters) - Sen. Hillary Clinton sharpened her attack on Friday against rival Barack Obama before new contests for the Democratic presidential nomination, casting herself as a champion of the U.S. middle class and saying voters faced a choice between "speeches and solutions."
Clinton, under pressure to slow Obama's momentum after eight consecutive losses, honed her economic message to appeal to middle- and lower-income voters before the next round of Democratic contests in Wisconsin and Hawaii on Tuesday and Texas and Ohio on March 4.
