Liberals celebrated a win Tuesday in the congressional district left vacant by Rep. Paul Hodes (D-N.H.).
Their candidate, Anne McLane Kuster, defeated Katrina Swett by running from the left.
With 13 percent of the precincts reporting, Kuster won the Democratic primary with 74 percent of the vote.
The race was a narrative that was tailor made for liberals nationwide. Swett is the daughter of the late Rep. Tom Lantos (D-Calif.) and the husband of former Rep. Dick Swett (D-N.H.). She was also the co-chairwoman of Sen. Joe Lieberman's (I-Conn.) 2004 presidential campaign.
Kuster raised significant amounts of cash from liberal activists nationwide and her candidacy was propped up by the newly-former Progressive Campaign Change Committee and liberal blogs like Daily Kos.
Swett worked to paint herself as the more electable candidate in a general election ahead of the primary, repeatedly pointing out Kuster's branding of herself as "progressive." It was a line that Kuster used to raise more cash online from liberal activists.
The wars in Iraq and Afghanistan and a back and forth over the extension of the Bush tax cuts dominated the final days of the primary campaign.
The Republican primary has not been called yet.
