The 2008 presidential campaign had a lot to do with Clinton's decision to weigh in on the Member-vs.-Member primary between Democratic Reps. Jason Altmire and Critz. Altmire stayed neutral, despite much courting from Clinton. Critz benefited from the fact that his old boss, Murtha, had endorsed Clinton in that race.
Clinton has a history of playing well in Pennsylvania, and his nod was critical to Critz's victory.
Maryland's 6th: April 3 Win Candidate: John Delaney Ties to Clinton: Fundraiser for Clinton's 2008 presidential campaign
When Maryland released its redistricting map, Delaney was not the establishment favorite.
State mapmakers drew new Maryland lines with a state legislator in mind.
And then the Maryland political world was stunned when Clinton endorsed unknown millionaire businessman Delaney. Overnight, Delaney gained instant credibility, and the race became his to lose.
His rival, state Senate Majority Leader Rob Garagiola countered with an endorsement from Gov. Martin O'Malley, but the momentum was set and the damage was done.
California's 30th Winner: To be decided in the fall Candidate Supported: Rep. Brad Sherman Ties to Clinton: Endorsed Clinton during the 2008 Democratic presidential primary
This is the lone outstanding race where Clinton has endorsed. After emerging from California's jungle primary as the top two, Sherman and Rep. Howard Berman are running against each other for a second time, with the winner of the Nov. 6 contest set to return to Congress next year.
Clinton has not exactly endorsed Sherman, but he wrote Sherman a "letter of support" more than a year ago.
For now, Sherman has the edge, and Bill Clinton's image has been squarely on his website for months.
