http://www.swingstateproject.com/diary/7204/ctgov-lamont-leads-allQuinnipiac (7/7-13, likely primary voters, no trend lines):
Tom Foley (R): 48
Mike Fedele (R): 13
Oz Griebel (R): 7
Undecided: 32
(MoE: 3.4%)
Ned Lamont (D): 46
Dan Malloy (D): 37
Undecided: 16
(MoE: 3.8%)
Since Quinnipiac has shifted for the first time to a likely primary voter model away from merely registered voters, I'm leaving out any trend lines (though you can see their last primary poll here). However, Quinnipiac also tested the primaries without a likely voter screen, which resulted in a 43-9 lead for Foley over Fedele and a 46-26 lead for Ned Lamont over Stamford Mayor Dan Malloy.
Lamont is also looking pretty good in the general election -- and so is Dan Malloy (registered voters, 1/14-19 in parens):
Ned Lamont (D): 49 (41)
Michael Fedele (R): 27 (32)
Undecided: 19 (23)
Ned Lamont (D): 45 (38)
Tom Foley (R): 33 (36)
Undecided: 17 (21)
Ned Lamont (D): 49
Oz Greibel (R): 25
Undecided: 21
Dan Malloy (D): 49 (37)
Michael Fedele (R): 26 (31)

Dan Malloy (D): 44 (37)
