Two weeks ago, a Quinnipiac poll showed Ned Lamont taking the lead over Joe Lieberman in Connecticut's Dem Senate primary for the first time. Lamont, at the time, was ahead, 51% to 47%.

His lead's a little bigger now. OK, more than a little.

Millionaire businessman Ned Lamont has extended his lead against veteran Sen. Joe Lieberman less than a week before Connecticut's Democratic primary, according to a new poll released Thursday.

Lamont, a political novice, has support from 54 percent of likely Democratic voters in the Quinnipiac University poll, while Lieberman has support from 41 percent of voters.

"Sen. Lieberman's campaign bus seems to be stuck in reverse. Despite visits from former President Bill Clinton and other big name Democrats, Lieberman has not been able to stem the tide to Lamont," said Quinnipiac University Poll Director Douglas Schwartz. He added, "Three months ago, Lamont was virtually unheard of, except perhaps on the blogs. As Democrats get to know Lamont better, they like what they see. Lamont has established himself as a credible alternative to Lieberman."

It's reached a point in which Lieberman is already crafting a plan in response to losing next Tuesday's primary.
