Political career and community involvement
Cappiello’s political career began in 1993 when at the age of 25, he was elected to the Danbury Common Council. In 1994, he won election to the Connecticut House of Representatives in a contest for the 138th District seat being vacated by Republican Mark Nielsen, who was running for the State Senate. He was easily re-elected to the State House in 1996. In 1998, Cappiello announced he was vacating his seat in the Connecticut House to run for the State Senate in the 24th District, where Mark Nielsen was retiring to challenge freshman Congressman James H. Maloney. He defeated Democrat Paul Estefan in a landslide, 62.24% to 37.76%, and was re-elected in 2000, 2002, 2004, and 2006. In the legislature, Cappiello’s priorities included open space and environmental preservation, support for non-profit service providers, public safety, and health care reform. His legislative accomplishments include the state preservation of of open space land at the Bogus Farm in Bethel, a comprehensive legislative review of the State’s Homeland Security preparedness, and a law that requires all newborn babies be screened for life-threatening metabolic disorders. He also led the successful effort in 2008 to thwart a scheduled increase in the state’s gas tax. In 2006, Cappiello was honored by the AARP for his leadership in preserving prescription drug coverage for thousands of Connecticut senior citizens. A strong fiscal conservative, Cappiello was tapped in 2005 to serve as the ranking Republican member of the General Assembly’s Appropriations Committee, which is responsible for writing the state’s biennial budget. He is a fierce proponent of the state’s spending cap and a vocal critic of Connecticut's high tax burden, and has voted in opposition to four state budgets due to tax and spending increases. As ranking member of the budget panel, Cappiello was instrumental in the successful Republican effort of 2007 to pass a "no tax increase" budget, despite initial opposition from legislative Democrats. Cappiello is heavily involved in many civic and cultural organizations, including the Danbury Lebanon American Club, Amerigo Vespucci Lodge, Danbury Lions Club, Danbury Land Trust, American Red Cross of Western Connecticut, Portuguese Cultural Center, and St. Anthony’s Maronite Church.
2008 Congressional race
On April 18, 2008, David Cappiello filed a campaign committee with the Federal Election Commission to challenge Democratic U.S. Representative Chris Murphy. On May 10, 2008, Cappiello was officially chosen as the Republican nominee at the Fifth District nominating convention in Southbury. Cappiello’s candidacy drew the attention of the National Republican Congressional Committee and political observers. The Washington Post’s political blogger Chris Cillizza named Cappiello one of the "Top 2008 Recruits", and in October 2007, Cappiello was included in the NRCC’s Challengers Helping Obtain the Majority Program to help raise funds for select candidates challenging incumbent Democratic members of Congress. On June 9, 2008, Cappiello announced his campaign had raised over $1,000,000 for his challenge to Murphy. During the campaign, Cappiello focused on economic issues, both in his own policy statements and in his criticisms of his opponent’s record. He supported eliminating earmarks from the federal budget and extending the 2001 and 2003 tax cuts Cappiello criticized Murphy on both accounts, pointing to Murphy’s failure to support a Congressional earmark moratorium despite claims during his 2006 campaign that he’d support ending the practice. Cappiello supported lifting the ban on offshore oil and gas exploration, increased construction of nuclear power plants, and reform of the oil futures market in addition to conservation and renewable energy measures, calling American reliance on foreign oil "a matter of personal, economic, and national security.". On Election Day, Cappiello was defeated by the incumbent Murphy.
