Hmm, did passing gun control save Malloy due to swings near Newtown?
Malloy increased his margin of victory by 20,000 votes from 2010 to 2014. There wasn't a pronounced GOP swing elsewhere in Connecticut from which Fairfield County could have "saved" Malloy. Most of the swing near Newtown is actually from Danbury - its mayor was Foley's running mate in 2010.
I will note, however, that the only Republican state legislator to lose reelection, Michael Molgano, was also the only Fairfield County representative to have voted against Malloy's gun bill.
