Campaign

Kweisi Mfume, a former congressman and NAACP President, was the first to announce for the position, in March 2005. Ben Cardin, then a congressman since 1987, was the only other major candidate until September 2005, when former Baltimore County Executive Dennis F. Rasmussen, American University professor Allan Lichtman, and wealthy Potomac businessman Josh Rales entered the contest. Thirteen other candidates subsequently also entered the primary. As of August 2006, Cardin had raised more than $4.8 million and collected endorsements from a number of Democratic politicians, the AFL–CIO, and The Washington Post; Mfume had raised over $1.2 million and collected endorsements from the Maryland State Teachers Association, Progressive Maryland, former Maryland Governor Parris Glendening, the National Organization for Women, and Maryland Congressmen Elijah Cummings and Al Wynn.

2006 United States Senate election in Maryland

On August 31, 2006, Maryland Public Television (MPT) and the League of Women Voters (LWV) sponsored a debate between the two leading Democratic Primary Candidates. The LWV of Maryland and MPT arbitrarily excluded most of the FEC qualified candidates from the only televised debates in the primary election. There were 18 candidates in this race, only 2, Ben Cardin and Kweisi Mfume, were allowed to debate, despite the strenuous protests of the excluded candidates. Lichtman, Rales, and Rasmussen petitioned MPT and LWV for inclusion in the debate, but received no response. On the day of the debate, Lichtman, his wife, and a campaign aide were arrested for trespassing while protesting during the taping of the debate. They were found not guilty on all charges. The judge in the case said it should never have been brought to court and was a gross violation of the parties' constitutional rights.

2006 United States Senate election in Maryland

Campaign

Michael S. Steele was expected to win the Republican primary, and the Baltimore Sun wrote the month before that he faced "only nominal opposition". Among a field of nine other candidates, the only Republican receiving sufficient media coverage was Daniel Vovak.

Results

General election

Candidates

Michael S. Steele (R) – lieutenant governor

Ben Cardin (D) – U.S. congressman

Kevin Zeese (G) – (Campaign website). Zeese won the nominations of the Maryland Green Party, the Libertarian Party of Maryland, and the Populist Party of Maryland, the first time all three parties had nominated the same candidate. However, a Maryland law passed in April 2006 prohibited such fusion candidacies, so Zeese, who was a registered Green Party member, was listed on the ballot as only the Green Party candidate.

Campaign

This was Maryland's first open Senate seat since 1986, when junior Senator Barbara Mikulski was first elected.
