Toiling behind Hillary Rodham Clinton in most national polls, her two main rivals in the 2008 Democratic presidential field, Illinois Sen. Barack Obama and former North Carolina senator John Edwards, are increasingly seeking to contrast themselves with the New York senator. Clinton is not only well known but well liked by Democrats. A recent Pew poll showed 88 percent of Democrats have "favorable" views of her, and 38 percent "very favorable," both higher numbers than Obama and Edwards scored. "Hard-edged attacks can cut both ways, particularly if you're attacking someone with an 88 percent approval rating among Democrats," said Stephanie Cutter, a Democratic strategist.Howie P.S.: We should all thank the WaPo for informing us that Hillary is "well-liked" and "in the strongest position," while her main opponents are "toiling." And that "angry Barack" photo is neat.
