As a former politcal operative I can speak with some authority on this. The only polls that mean anything right now are the internal polls done by the campaigns, and they don't relaese those. If they DO release them, the results have, shall we say, been "edited" to create the impression of momentum or just to gin up a headline. Beyond that the polls done by anyone else mean nothing and are not worth the electrons it takes to send them around cyberspace.
My take: Lieberman will trash Lamont in the general. This is not due to any polling or whatnot but because 1) Lamont is an idiot; 2) Lieberman is not; and 3) JL has a statewide network on the ground and a LOT of CT pols owe him their jobs.
Both campaigns will bribe ... er, enter into contractual arrangement with different "independent" polling groups to produce the desired poll numbers to be released for public consumption.
Bottom line THERE IS NO WAY Lieberman could either a) have sprinted to a 12-point lead in less than a week or b) have LOST that lead in less than a week.
As I stated on a different thread, bovine scatology is still bovine scatology, no matter how many moonbats believe it.
