John Adler

Only a few months after leaving the House due to losing reelection, Adler unexpectedly died after suffering from endocarditis as a result of getting a staph infection. In 2012, his widow, Shelley Adler, announced her candidacy for the seat, but she ended up losing to Runyan.

In 2012, Shelley Adler unsuccessfully ran against Runyan for Adler's old U.S. House seat.

In March 2011, Adler contracted a staph infection which resulted in endocarditis, leading to emergency heart surgery. He never recovered and died on April 4, 2011.

Adler lost the 2010 midterm election to Republican nominee Jon Runyan. Adler received 47.3% of the vote, while Runyan received slightly more than half the votes cast. Runyan is a former Philadelphia Eagles star and a Mount Laurel resident.

Some Democratic operatives asserted that Adler campaign staffers and the Camden County Democratic Committee (CCDC) recruited Tea Party candidate Peter DeStefano in an attempt to split the conservative vote and benefit Adler. New Jersey Tea Party groups said they had never heard of DeStefano until he had a strong showing in a July poll released by the Adler campaign. On October 8, 2010, the Associated Press reported, based on the details of an earlier article at CourierPostOnline.com, that there was "mounting evidence" that the Democrats recruited DeStefano. The article noted that a Democratic Party employee ran DeStefano's website and that many of the signatures on DeStefano's nominating petitions belonged to Democrats - including a former Adler campaign staffer. Reportedly, Steve Ayscue, the paid head of operations for CCDC, and Geoff Mackler, Adler's campaign manager, presented a plan at CCDC Headquarters during a May 26 meeting of the South Jersey Young Democrats, and some of those present soon joined in circulating a petition to place Peter DeStefano on the ballot. Adler denied the allegations. DeStefano called the suggestion that he was a Democratic plant "a bunch of crap". In the end, DeStefano garnered only 1.5% of the vote.

Adler was in favor of the American Recovery and Reinvestment Act. Adler voted against the Troubled Asset Relief Program (TARP), and later voted to end the program. In January 2009, Adler announced his first bill as a U.S. Representative: the Safeguarding America's Seniors and Veterans Act, which mandated a one-time payment of $500 to persons eligible for Social Security, railroad retirement, or veterans disability benefits. According to a statement by Adler's office, the bill was necessary because "the American Recovery and Reinvestment Act of 2009 fails to address the needs of our seniors and veterans". The bill attracted 11 cosponsors; it was referred to the House Veterans Affairs Subcommittee on Health, and progressed no further. Adler voted for the Dodd–Frank Wall Street Reform and Consumer Protection Act.

In November 2009 and March 2010, Adler voted against House and the Senate Health Care bills. He did not sign a petition circulated by Iowa Republican Steve King calling for a complete repeal of the law.

The 3rd district race was the last one to be called in New Jersey on Election Night 2008. Adler ultimately defeated Myers with 52.08% of the vote to Myers' 47.92%. He was sworn into his position as the Congressman from the 3rd district of New Jersey in the United States House of Representatives on January 6, 2009, the first Democrat to represent this district in 123 years. The district was the 1st for most of the time until 1967, then was the 6th from 1967 to 1983, the 13th from 1983 to 1993, and has been the 3rd since 1993.

Republicans heavily targeted this seat in this election cycle. A warning sign for Adler came in the New Jersey gubernatorial race in 2009, when Republican candidate Chris Christie carried Adler's district by 17 points over Democratic Governor Jon Corzine Governor Christie campaigned hard for Runyan, calling Adler a "career politician".

Adler co-sponsored a bill that would expand voting rights for military personnel and New Jersey citizens overseas to include state and local elections. The bill was signed into law on August 12, 2008, by Governor Corzine.

On September 20, 2007, Adler announced that he planned a second challenge to Saxton. By this time, the district had been renumbered as New Jersey's 3rd congressional district . The district stretches from the suburbs of Philadelphia to Ocean County. On November 9, 2007, Saxton announced that he would not seek reelection in 2008, citing prostate cancer. This dramatically altered the dynamics of the race; instead of facing a 25-year incumbent, Adler was now running in an open seat. Adler was unopposed in the Democratic primary, and faced Republican Medford Mayor, Lockheed Martin executive, and Gulf War veteran Chris Myers. Adler held a financial advantage over his opponent through all of the race, holding a 10–1 or 5–1 funding edge over Myers for a majority of the campaign. Adler had raised the most money in the country of any non-incumbent congressional candidate.

Adler was co-sponsor of the New Jersey Smoke-Free Air Act, enacted in 2006, which banned smoking in almost all public places. Adler was one of three co-sponsors of a Senate bill submitted in 2008 that would extend the smoking ban to casinos and simulcasting facilities, which had been exempted in the earlier version of the ban.

Similar to in 2004, State Senator Adler was one of the first elected officials in New Jersey to go against the party establishment in his presidential endorsement during the 2008 election cycle. He endorsed Barack Obama for the Democratic presidential nomination when the majority of other New Jersey Democratic politicians supported initial frontrunner Hillary Clinton. Like with Kerry instead of Dean, Obama, who was Adler's choice, would go on to become the Democratic nominee instead of Clinton.

On October 7, 2003, the then-State Senator Adler (along with Representative Bill Pascrell of New Jersey's 8th congressional district) formally endorsed Massachusetts Senator John Kerry for President in 2004 and became the co-chairman of his campaign in the state. Shortly afterwards, on December 19, 2003, Governor Jim McGreevey and most of the rest of the New Jersey Democratic Party came out in support of former Governor of Vermont Howard Dean for President. Because of Adler's endorsement of Kerry, and Kerry's decisive win in the Democratic Primary, Adler was rumored to be the frontrunner for U.S. Attorney for New Jersey if Kerry were to win the 2004 presidential election (which he did not).

Adler was elected in 1991 to the New Jersey State Senate, where he served from 1992 until his inauguration into the U.S. House of Representatives in 2009. While in the New Jersey State Senate, Adler served on the Judiciary Committee (as Chair) and the Environment Committee. He served on the New Jersey Israel Commission since 1995, and on the New Jersey Intergovernmental Relations Commission from 1994 to 2002.

In 1990 Adler challenged incumbent Jim Saxton for his seat in New Jersey's 3rd Congressional District. Adler was defeated by Saxton by a margin of 60% to 40%.

From 1988 until 1989, Adler served on the Cherry Hill Township Council. While serving on the Council, Adler passed the township's ethics ordinance.

Adler met his wife Shelley while at Harvard Law School. He converted to her faith of Judaism in 1985, having been raised an Episcopalian. After they graduated, they returned to South Jersey and settled down in Cherry Hill. They resided in Cherry Hill with their four sons until his death.
