Indiana Democrats are questioning Gov. Mitch Daniels's (R-Ind.) foreign-policy credentials after he told reporters he likely isn't ready to face President Obama in a debate on international issues.

Daniels, who is on an East Coast swing, is weighing a bid for the GOP's 2012 presidential nomination. During a discussion with reporters in New York on Tuesday, the governor said he was "probably not" ready to debate Obama on foreign policy.

"His foreign-policy details are TBD," wrote National Review Online's Ramesh Ponnuru.

The Indiana Democratic Party blasted a link to the NRO article to its press list and said that Daniels "vastly underestimated the cost of the the Iraq War when he was serving as President George W. Bush's OMB director."

Daniels is set to deliver a speech on education Wednesday afternoon in Washington.
