Sanders is counted as a Democrat.
Red = Obama overperformed Democratic Senate candidate
Blue = Democratic Senate candidate overperformed Obama
Green = Both (or neither) major-party candidates outperformed Obama and Romney
Gray = no Senate election
Hatch was the only incumbent who underperformed their party's nominee (Feinstein and her opponent both outperformed Obama/Romney and Cardin and his opponent both underperformed Obama/Romney).
Comments? Somewhat deceptive with more Democratic incumbents up, both it appears Dems had stronger Senate nominees.
