Obama Supporter Questions McCain's Judgment, Age

From CBS News' Maria Gavrilovic:

(DUBLIN, OHIO) Obama surrogate, Sen. Sherrod Brown, D-Ohio, subtly referenced John McCain's age tonight as he questioned his judgment for choosing Alaska Gov. Sarah Palin as a running mate.

"John McCain chose someone who was a mayor of a town of 7,000 people, then was elected... Governor of a state that's half the population of Franklin County," Brown said when introducing Obama at the "Road to Change" rally.

"And yet she's gonna be a heartbeat away from the president. No way, no way is right!"

Obama and his surrogates have been careful not to call McCain's age into question, but that appears to be changing as the presidential campaign becomes increasingly tense. Despite Brown's tone tonight, both Obama and Biden have showed restraint when it comes to criticizing Palin.

"She's got a great story. She seems to have a wonderful engaging personality," Obama said at a press conference, adding that Palin's shortcoming is her support for McCain's policies.

However, Obama urged the press to compare Palin's record with Biden's, suggesting that he may have made a better choice for a running mate. "I feel confident about my choice. I'll let JM talk about his," Obama said.
