Of course it does. It siphons votes away from the J.P. Morgan heir.
In case anyone is wondering, the Connecticut Republicans made a mistake earlier this year, selecting a near-nonentity as the Republican nominee, under the assumption that Joseph Lieberman would be unbeatable.....and so barring some cataclysmic event, the Republicans aren't even in this race.
It's between the incumbent senator Joseph Lieberman and the Wall Street scion, the Republican candidate being immaterial. But it is possible the Republican candidate and the wealthy one will run neck-and-neck now, for the distant second place.
Saw in another article yesterday, the Dems are not targeting the Connecticut race for cash support because Lamont has his own money, and either way (Lamont/Lieberman) they figure it's a win-win situation for them.
I also read elsewhere where Lieberman plans to caucus with the Dems after the election. No surprise there.
