<P> Jefferson - Jackson Day is the annual fundraising event (dinner) held by Democratic Party organizations across the United States . It is named after Presidents Thomas Jefferson and Andrew Jackson, whom the party regards as its distinguished early leaders . </P> <P> The song "Happy Days Are Here Again" is the unofficial song of the Democratic Party . It was used prominently when Franklin D. Roosevelt was nominated for president at the 1932 Democratic National Convention and remains a sentimental favorite for Democrats today . For example, Paul Shaffer played the theme on the Late Show with David Letterman after the Democrats won Congress in 2006 . "Don't Stop" by Fleetwood Mac was adopted by Bill Clinton's presidential campaign in 1992 and has endured as a popular Democratic song . The emotionally similar song "Beautiful Day" by the band U2 has also become a favorite theme song for Democratic candidates . John Kerry used the song during his 2004 presidential campaign and several Democratic Congressional candidates used it as a celebratory tune in 2006 . </P> <P> The 2016 campaign of Democratic Party presidential candidate Bernie Sanders used the hopeful Simon & Garfunkel song "America" for one of its campaign advertisements, with the complete permission of the still - active duo of popular American musicians . As a traditional anthem for its presidential nominating convention, Aaron Copland's "Fanfare for the Common Man" is traditionally performed at the beginning of the Democratic National Convention . </P> <P> The Democratic National Committee (DNC) is responsible for promoting Democratic campaign activities . While the DNC is responsible for overseeing the process of writing the Democratic Platform, the DNC is more focused on campaign and organizational strategy than public policy . In presidential elections, it supervises the Democratic National Convention . The national convention is subject to the charter of the party and the ultimate authority within the Democratic Party when it is in session, with the DNC running the party's organization at other times . The DNC is chaired by former Labor Secretary Tom Perez . </P>
