Obama and Former South Carolina Sen. John Edwards faced a barrage of heckles and boos from the rowdy Las Vegas audience when likening Clinton to Republican candidates and linking her to what they called a corrupt Washington system.
"This is the kind of thing I would expect from Mitt Romney or Rudy Giuliani," Obama said of Clinton's tax cut stance, struggling to make himself heard over the crowd's boisterous defense of Clinton.
Edwards faced an even harsher audience response when he asserted, "Senator Clinton defends the system, takes money from lobbyists, does all those things."

Dean said the audience's unfavorable reactions to the attacks worked well to putsuch things to a stop and made his job easier as a representative of the Democratic Party.
"The best thing that happened was that when the attacks were going on among the candidates the audience sort of stepped in and made it clear that they didn't want to hear any more of it," Dean said. "One of my jobs was being the referee, but the audience did that for me and I was very pleased about that."
