Over at MassPoliticsProfs, Maurice Cunningham says there is a lot more luck involved in election outcomes than most of us allow, and considers what political scientists John Sides and Lynn Vavreck call "choice and chance" in this election:

Baker was lucky and Coakley was very unlucky that the Republican Governor’s Association made the choice to spend wildly in support of Baker’s campaign, while the Democratic Governors Association chose to sit on its fat wallet and not spend in a winnable race for Coakley.
