Source: Clinton Serious About SoS

A person close to Sen. Hillary Rodham Clinton says she would seriously consider serving as Secretary of State if an offer was made -- adding, "I wouldn't bet against" her accepting a cabinet invitation.

Clinton, the person said, had been hearing rumors about the State Department job for about a week, but didn't take it seriously -- until Obama's transition team initiated serious discussions in the last day or two.

"She didn't ask for it," added the source. "It was all from their side."
