What do they make of a Lieberman win in CT? Do they count him as a democrat? many polling sites are doing that to make it appear that the democrats are doing better.
Since Lieberman will still caucus with the Dems if he wins, it makes sense to do it that way.
Owise has separate predictions on independent vs. dem vs. repub. Owise is not lumping leiberman or other indy in with democrats as far as the percentage chance of control. Tradesports.com, however, requires that GOP maintain a "true" majority of 51 seats. So there are slight differences between what probabilities each one is measuring.
I would count him as a Dem, because he will be one when he wins.
