Prince George’s County State’s Attorney Glenn Ivey (D) is forming an exploratory committee in the coming days for a possible primary challenge to 4th district Rep. Donna Edwards (D).

Ivey, a former senior staffer on Capitol Hill who was appointed chairman of the Maryland Public Service Commission by former Gov. Parris Glendening (D), is a well-known figure in Prince George’s politics who was also viewed as a possible contender for the county executive post next year.

Ivey said he has a desire to return to Capitol Hill, where he worked in the 1980s and 1990s.

“With Obama in the White House and Democratic majority in the Senate and the House, there’s a great opportunity for moving a progressive agenda forward,— he said in an interview Wednesday.

Ivey said he expects a Congressional bid will cost at least $1 million, and he won’t be able to self-fund his campaign.

Edwards knocked off then-Rep. Albert Wynn in the 2008 Democratic primary after narrowly losing to him in 2006. She won a special election in the 4th district after Wynn resigned in the wake of his primary loss. As of Sept. 30, Edwards reported just under $56,000 in cash on hand in her campaign account.

State Del. Herman Taylor (D) is also contemplating entering the Congressional primary.
