There is no shortage of post-mortems on Lamont’s Connecticut victory in today’s blogs and rags, addressing his win from every conceivable issue-angle. For a high-profile contest, however, the reporting on who voted for each candidate has been somewhat sketchy. Connecticut papers do offer a few clues. An editorial by the Hartford Courant, which endorsed Lieberman, noted:

…the unprecedented rush of registered unaffiliated voters and new voters to the Democratic Party in Connecticut in recent weeks is a phenomenon that should keep Karl Rove awake at night.

The Courant reported that more than 40 percent of eligbile voters turned out, 15 percent more than the last Connecticut Democratic primary, a 1994 contest for the gubernatorial nomination. Writing in The Connecticut Post, Peter Urban and Michael P. Mayko note that 28,886 voters were “newly registered or switched from unaffiliated since May 1.
Mark Pazniokas of The Hartford Courant offers this assessment:

Lamont rolled up lopsided margins in the Farmington Valley, Litchfield County, the lower Connecticut River Valley and scattered suburbs around the state. He won Hartford and Lieberman’s hometown of New Haven, which first elected Lieberman to the state Senate in 1970.
Lieberman dominated in the New Haven suburbs, the struggling rural towns of eastern Connecticut and old mill towns of the Naugatuck Valley, home of conservative Reagan Democrats and the place he chose to begin his campaign bus tour 10 days ago. He also took Bridgeport.

Mystery Pollster Mark Blumenthal has a few insights in his “Connecticut Epilogue,” including:

The geographic turnout patterns are also relevant. Charles Franklin has already posted an amazingly thorough (and graphical) turnout analysis of the turnout showing that Lieberman did better in the larger towns and cities, while Lamont did better in less urban areas. He also confirms the so-called “Volvo/donut” turnout pattern suggested yesterday by Hotline On-Call, that turnout was higher in the smaller towns where Lamont had an advantage, lower in the larger towns where Lieberman did better (see also Hotline’s follow-up analysis this morning).

Looking toward the future, As an Independent, Lieberman hopes to win voters from Connecticut’s 453,715 Republican and 929,005 unaffiliated registered voters. But if he takes the higher road of affirming Democratic party unity, Lamont should hold the seat for the Democrats.
