Deval Patrick (D-inc): 41
Charlie Baker (R): 36
(MoE: ±4.5%)
Add Deval Patrick of Massachusetts to the list of northeastern Governors that nobody much likes. Patrick's job approvals are 42% approve (including 11% strongly approve) and 57% disapprove (including 32% strongly disapprove). He finds himself in a dead heat with businessman Christy Mihos (who garnered 7% of the vote in 2006 as an independent, but is running as a Republican this time) and barely leading Charlie Baker (whom I'll admit I've never heard of before today; he's the CEO of health care provider Harvard-Pilgrim, and is rumbling about the race while not having taken any steps yet). Mihos is well-known with 46/35 favorables, while Baker is only at 37/27 with 35% unknown.
Patrick represents a state that's heavily Democratic enough that his opposition may already be polling near their ceilings... but given the state's recent tolerance of moderate Republican governors (and its bamboozlement by Mitt Romney), he can't even begin to count on the state's lean to pull it out for him. One other item that gives me some confidence about this race, though, is that Patrick has hired David Plouffe to run his re-election campaign, while Christy Mihos has hired... Dick Morris.
