On a day when the latest Quinnipiac poll showed Ned Lamont losing ground in the race against Sen. Joseph Lieberman, Howard Dean's presence at a boisterous Democratic rally Friday couldn't have been more timely - or necessary. Dean, the zealous chairman of the Democratic National Committee and former presidential candidate from Vermont, both railed against the Bush administration and exhorted the crowd of supporters and campaign volunteers to work their hardest until Election Day. "Now we've got 18 days left. Eighteen days of knocking on doors. I know you all know how to do that, because you did it for Ned Lamont before the primary," Dean said. "Work like crazy. Some of you might drop dead, but I promise you on Nov. 8, the resurrection will occur."If the poll released Friday is correct, Lamont will need every drop of energy his supporters have before Election Day. According to that poll, Lieberman now holds a 52 percent to 35 percent lead over Lamont among likely voters, a 17-point advantage. Lamont was only trailing Lieberman by 10 points at the time of the last Quinnipiac poll, which was released Sept. 28. The Republican candidate in the race, Alan Schlesinger, picked up two percentage points, going from 4 percent to 6 percent. Seven percent of voters polled said they are still undecided.
