Failed 2006 Connecticut Democratic Senate nominee Ned Lamont will campaign for 1st district candidate Chellie Pingree (D) next weekend.

Lamont, a wealthy businessman, used his own money and a groundswell of support from liberal Web-based supporters to defeat Sen. Joe Lieberman (ID-Conn.) in last year’s Democratic primary. Lieberman later won the general election running as an Independent.

Pingree is seeking to replace Rep. Tom Allen (D-Maine), who is running for Senate next year. Democrats are favored to hold the Portland- and Augusta-based seat.

On Aug. 12, Lamont will appear at campaign events in Harpswell and Portland with Pingree, a former state Senate Majority Leader and one-time president of Common Cause.

In addition to Pingree, several other Democrats are running, including York County District Attorney Mark Lawrence, former state Senate Majority Leader Michael Brennan and Adam Cote, an Iraq War veteran.

Pingree lost her 2002 bid to unseat Sen. Susan Collins (R), whom Allen is challenging next year.
