A look at key races in Tuesday's primaries in 9 states
Governor: Len Munsil, former head of an advocacy group for Christian conservatives, won the Republican nomination to challenge Democratic Gov. Janet Napolitano, who was unopposed in her primary. Munsil's opponents included Don Goldwater, nephew of the late Barry Goldwater, former senator and presidential candidate.
House: Conservative Republican Randy Graf won the party's nod to replace GOP Rep. Jim Kolbe, who is retiring. National Republicans jumped in to support a more moderate rival, state Rep. Steve Huffman, worried the seat might go Democratic if a conservative candidate won.
DISTRICT OF COLUMBIA:
Mayor: City Council member Adrian M. Fenty beat longtime council Chairman Linda W. Cropp for the Democratic nomination for mayor. In the heavily Democratic city, the primary is tantamount to the general election.
Senate: Rep. Ben Cardin beat Kweisi Mfume, former head of the NAACP, for the nomination to run for Paul Sarbanes' seat. Cardin will face GOP Lt. Gov. Michael Steele, who — if he wins in November — would be the lone black Republican in the Senate.
Governor: No primary opposition for either GOP Gov. Robert Ehrlich or Democrat Martin O'Malley, Baltimore's mayor.
Comptroller: Voters rejected William Donald Schaefer's bid for another term as state comptroller. Anne Arundel County Executive Janet Owens and state Delegate Peter Franchot battled for the lead, with Schaefer in third place.
Governor: GOP Gov. Tim Pawlenty and Democrat Mike Hatch, the state attorney general, easily won their parties' primaries. Peter Hutchinson, a consultant who once ran Minneapolis public schools, emerged from the Independence Party primary to join a three-way race in November.
House: State legislator Keith Ellison edged out three rivals to win the Democratic nomination for a Minneapolis-area district, raising his chances of becoming the first Muslim member of Congress in November.
State Senate: GOP State Sen. Paul Koering, who revealed he was gay, beat back a primary challenge from city Councilman Kevin Goedker, who asked voters to decide the race based on their values but said he was not opposing Koering because he's gay.
Senate: Democratic Sen. Hillary Clinton easily beat little-known anti-war candidate Jonathan Tasini. She will face former Yonkers Mayor John Spencer.
Governor: With an open governor's seat, Democratic Attorney General Eliot Spitzer overwhelmingly defeated primary challenger Tom Suozzi, Nassau County executive. Spitzer will face Republican John Faso, former state Assembly Minority Leader.
Attorney General: Former federal Housing Secretary Andrew Cuomo — son of former Gov. Mario Cuomo — beat Mark Green, the former New York City Public Advocate in the Democratic primary. Cuomo will face former Westchester County District Attorney Jeanine Pirro.
Senate: GOP Sen. Lincoln Chafee beat challenger Steve Laffey, mayor of Cranston, in a race that attracted national attention and money. A national anti-tax group backed Laffey. Senate leaders backed Chafee, worried his loss could allow Democrats to pick up the seat in the fall election.
Senate: As expected, Rep. Bernie Sanders won the Democratic nomination for Senate. Sanders, who plans to run as an independent, aims to win the seat of retiring Sen. James Jeffords, the Senate's lone independent. Businessman Richard Tarrant won the GOP nomination.
