Members of Frosh’s exploratory committee include Rep. Chris Van Hollen; Montgomery County Executive Isiah Leggett; Prince George’s County Executive Rushern Baker; former governors Parris Glendening and Harry Hughes; former Attorney General Stephen Sachs; and more than half of Frosh’s colleagues in the state Senate, including President Thomas V. Mike Miller Jr. (D-Calvert).

In an interview, Frosh said he would take the next several months to make a final decision about whether to run but added that he is “about 95 percent of the way there.”

“Unless something dramatic changes, I expect to run,” said Frosh, who is chairman of the Senate Judicial Proceedings Committee and widely viewed as one of the more cerebral members of the chamber.

Frosh is one of several Democrats who have been angling to succeed Attorney General Douglas F. Gansler (D), who is gearing up to run for governor in 2014.

Other Democrats who’ve been mentioned as possible candidates include Del. C. William Frick (D-Montgomery), Del. Jon S. Cardin (D-Baltimore County) and Del. Aisha N. Braveboy (D-Prince George’s).
