Comptroller Peter V.R. Franchot is expected to run for governor in 2014, a prospect discussed in this piece in The Washington Times in September.

County Executive Isiah Leggett (D) said last year that he would not seek re-election to the post that Duncan held for three terms.

Maryland Juice reported rumors in January that Duncan was considering a run for comptroller. The blog noted that Duncan would be part of an increasingly crowded field.

Duncan ran against Martin O'Malley for the Democratic nomination for governor in 2006 before dropping out, citing depression, as The Gazette reported.

Duncan was coy when asked by Rockville Patch earlier this month about his political future, saying that he needed to “get down to campaign fighting weight. Then we’ll see what happens.”
