That's alot of undecideds for 10 days out, and I suspect a big chunk of them will come home to Martha on election day.
Like they did for Buono?
Not really comparable. Christie was a popular incumbent governor with a 65% approval rating. The recent MassINC poll shows both Baker and Coakley are viewed favorably, but Baker moreso. And this also lays credence to the claim that other Dems wouldn't be doing better than Coakley at this point. She's not losing because of horrible favorability scores or something.
