Full Circle in Connecticut
From 1958 through 1970, the seat now held by Lieberman was occupied by Thomas Dodd (father of Lieberman's current colleague, Democrat Chris Dodd). Dodd was a hard-line anti-communist known for his Red-baiting speeches and strong support for the war in Vietnam. But he was censured for ethics violations in the late 1960s, and decided not to stand for re-election.
John Bailey, in an attempt to prove the continued power of the state Democratic machine, slated a colorless pro-war candidate as the machine nominee. But he was challenged in the primary (an unheard-of event for CT in those days) by the Ned Lamont of 1970--Joseph Duffey, an anti-war activist and high-ranking figure in the ADA. Duffey scored an upset in the primary, but then Dodd (with Bailey's quiet support) jumped back into the race as an independent. Dodd figured he could siphon off pro-war Dems from Duffey and get enough independents to narrowly prevail.
Unfortunately, Dodd and Duffey just wound up dividing the Democratic vote, and the race went to the third candidate--a one-term Republican congressman named Lowell Weicker, who won with a plurality. In 1970, Weicker ran as something of a Nixon supporter, though he quickly distanced himself from both the administration and the national party.
This maverick reputation allowed Weicker to survive a strong challenge from liberal Congressman Toby Moffett in a bad year for the GOP, 1982. So in 1988 the Dems decided to go with someone more centrist--Leiberman. In one of the year's two biggest Senate upsets (Conrad Burns' win in Montana was the other), Lieberman prevailed 51-49.
So, Lieberman, in effect, owes his seat to a schism within the CT Democratic Party over a foreign war, which set the stage for Weicker's initial election.
Will history repeat itself in 2006? As the Timesnoted, Lieberman's decision creates a problem for national Democrats. It probably makes Lamont the favorite for the primary--which is an amazing development. (Lamont is already cleverly playing the move, remarking,"I think he is trying to have it both ways, and on an awful lot of important issues over the last 18 years, he's tried to have it both ways.") But there's a big difference between 1970 and 2006. Weicker in 1970 was a credible, if largely untested, challenger. In 2006, the Republicans have put up a little-known former state representative. It's likely, therefore, that Lieberman will be re-elected, as an independent. I bet the GOP is kicking itself for not putting more emphasis on this race.
