What Do Yesterday's Primary Results Mean for the Future?

Veteran Senator Joe Lieberman lost to Ned Lamont in yesterday's Democratic primary with 48% to Lamont's 52. This morning Lieberman filed to run as an Independent in November's general election. Connecticut's other Democratic Senator, Chris Dodd, said that he would honor Lieberman's decision, but hopes that voters would unite and support Lamont. Wile all sides recognize the final result in Connecticut's senatorial primary, there's little agreement on what it means. Was it a referendum on the war in Iraq that means trouble for Republicans in other parts of the country, or will it hurt the Democrats most? Is it a sign that moderates are a vanishing breed in both parties, whichever ends up controlling the Congress next year? We hear from reporters and political strategists, pollsters and historians.
