Clinton and Obama spar over experience

By Kay Henderson

DES MOINES, Iowa (Reuters) - Democratic candidates Hillary Clinton and Barack Obama sparred over who has the most experience to be president on Monday as a new poll showed Obama narrowly leading in the crucial kick-off state of Iowa.

The Washington Post-ABC News poll showed Obama with the support of 30 percent of likely Democratic caucus-goers in Iowa, compared to 26 percent for Clinton, 22 percent for former Sen. John Edwards and 11 percent for New Mexico Gov. Bill Richardson.

The poll had a margin of error of plus or minus four percentage points, meaning that Obama's lead was within that statistical uncertainty zone.

Other polls give Clinton a slight edge in Iowa, which on January 3 opens the state-by-state battle to pick the Democratic and Republican contenders in the November 4, 2008, election. The last Washington Post-ABC News poll in Iowa, in late July, showed Obama with a one-point lead over Clinton.

As Americans prepared to celebrate the Thanksgiving holiday on Thursday, Clinton used a campaign speech in Knoxville, Iowa, to try to set herself apart from Obama and Edwards.

Without mentioning the other Democrats by name, Clinton suggested he rivals lacked the experience to take on America's economic challenges, saying "we can't afford on-the-job training for our next president."

"We need a president who understands the magnitude and complexity of the challenges we face, and has the strength and experience to address them from Day One," she said.

Obama dismissed Clinton's comments and questioned Clinton's experience. She was first lady when her husband, Bill Clinton, was president in the 1990s, and has been a New York senator for nearly seven years.
