DNC Chair: Politicians should admit mistakes

It's "refreshing" for voters to hear Democrats admit their mistakes, according to Democratic National Committee Chairman Tim Kaine.

"People are suspicious of us as politicians, thinking we're slick or will say whatever," Kaine said at a press conference Tuesday after attending the Iowa State Fair. "It can be refreshing to hear someone say, 'I've learned some things along the way, and I can always be better tomorrow than I am today.'"

Kaine was referring to Iowa Gov. Chet Culver's (D) admission this week that he was responsible for recent embarrassing episodes involving top state bureaucrats.

The DNC chairman was in Iowa for a state party fundraiser and to meet with activists. He said Democrats face some "tough" races in the Hawkeye State this cycle, despite dominating the GOP in 2008. 

"We had a great win in Iowa in 2008," Kaine said at a joint news conference with Culver, according to the Des Moines Register. "Now, we're looking at some races that are tough."

Culver is facing a stiff challenge from former Gov. Terry Branstad (R), and Des Moines-area Rep. Leonard Boswell (D-Iowa) is also considered vulnerable.
