I think you'd be forgiven if you've forgotten who all these players are, so let's give you a scorecard:
Susan Bysiewicz: CT Secretary of State (1998-)
Dan Malloy: Mayor of Stamford (1995-)
Ned Lamont: Businessman, '06 Democratic nominee for U.S. Senate
Tom Foley: Businessman, U.S. Ambassador to Ireland (2006-2009)
Michael Fedele: State Representative (1992-2002), Lt. Governor (2007-)
Republicans are hampered by extremely low name recognition here, but even Bysiewicz has room to grow (45% are "not sure" whether or not they approve of her). The candidate who arouses the most opinions, one way or the other, is Ned Lamont -- but his favorables are at 29-28, well below Bysiewicz's 39-16 spread. Ned Lamont closed his '06 campaign with some damaged favorables (29-36, with another 21% having "mixed" feelings, according to a Quinnipiac poll from late October of that year), so he'd have a bit of work to do in building a more appealing image for himself.
Still, though, it's hard not to like these numbers.
