Probably lots of Republicans and "centrists".
"So if the democrats don't want him, who does he think is going to vote for him?
Probably lots of Republicans and "centrists""
Some of the 49% of Democrats who DID want him.
Lots of Republicans who won't vote for a credibility-challenged guy with the gambling problem.
The Independents, who are the plurality in this state (there are more Independents than either registered Republicans or Democrats) and who have voted for Lieberman in the past.
It is easier for a non-partisan to vote for a non-partisan than a partisan, when the non-partisan is a respected and well-liked incumbent Senator, and the Republican and Democrat candidates are weak.
Who will vote for him? Lots of Republicans. Lots of Democrats. Jews of whatever party. Lots of Independents.
He'll win big.
And should.
