No - Connecticut is one of those sensible states where you have to register for a party to vote in its primary. Further the deadline to switch from Republican to Democrat was some time ago - May I think. However Independents were allowed to switch to Democrat at the last moment, and Lieberman is popular among Independents. Also, all these polls are fairly meaningless except as they show a trend. They depend on likely voter models, and it is extremely hard to predict who will vote in a primary - especially one that the media starts paying attention to at the last minunte. Obviously what the polls show about the trend is important (to those interested in the contest I mean) - that a long term trend against Lieberman has been at least partially reveresed. We'll know Tuesday. I suspect the election will be close, but no one really knows.. I will note that last week when everyone was talking about 13 point leads, Lamont's staff was leaking info that this was way overstated - that their internal polling consistently showed a lead within the margin of error.
