Wait a second...Something here makes absolutely no sense mathematically. If Lamont is leading Lieberman 51-41 in the primary, how can he be tied with Lieberman in the general? For this to happen, Lamont has to be only trailing by a slight margin among independents and Republicans.
Or you have a large (most likely, too large) sample of Democrats who will choose to back the party choice regardless of who they support in the primary.
Exactly. There is no reason to assume Lieberman could hold onto his entire primary election base in the general. There's every reason to assume he couldn't, in fact. (Which is not to say that this poll is exactly accurate either, of course.)
