The passion and energy fueling the antiwar challenge to Sen. Joseph I. Lieberman in Connecticut's Senate primary signal a power shift inside the Democratic Party that could reshape the politics of national security and dramatically alter the battle for the party's 2008 presidential nomination, according to strategists in both political parties.A victory by businessman Ned Lamont on Tuesday would confirm the growing strength of the grass-roots and Internet activists who first emerged in Howard Dean's presidential campaign. Driven by intense anger at President Bush and fierce opposition to the Iraq war, they are on the brink of claiming their most significant political triumph, one that will reverberate far beyond the borders here if Lieberman loses.
An upset by Lamont would affect the political calculations of Sen. Hillary Rodham Clinton (D-N.Y.), who like Lieberman supported giving Bush authority to wage the Iraq war, and could excite interest in a comeback by former vice president Al Gore, who warned in 2002 that the war could be a grave strategic error. For at least the next year, any Democrat hoping to play on the 2008 stage would need to reckon with the implications of Lieberman's repudiation. Even backers of the 2000 Democratic vice presidential nominee are now expecting this scenario. Two public polls in the past three days show Lamont with a lead of at least 10 percentage points.
