The chair of the Democratic National Committee on Saturday said President Obama's re-election last month was a "crowning achievement" for the Democrats.

Florida Congresswoman Debbie Wasserman Schultz, speaking to the party's executive committee at the Montage Deer Valley, said it seemed to some that the contest between Obama and Republican Mitt Romney was tight as Election Day approached.

"Guess what, it wasn't close," she said, noting that Obama won some of the swing states by wider margins than had been anticipated.

Wasserman Schultz praised the Democratic grass-roots campaign effort, which stretched through the 50 states. They rallied voters on a door-to-door basis and organized phone banks, she said. The party supporters "knocked on doors until their knuckles bled," Wasserman Schultz said.

Romney offered what she labeled a repeat of trickle-down economics. Obama countered with long-range economic ideas, she said.

Wasserman Schultz, meanwhile, told the Democrats the president is supporting the middle class in the negotiations about the nation's fiscal situation. She said Obama bases decisions on what is best for the middle class.

"We must give the middle class the certainty they deserve," she said about taxes, urging the crowd to keep pressure on the Republicans.
