Obama easily carried Delaware by 18.63 points. Throughout the campaign, news organizations considered Delaware a state Obama would win, or a safe blue state. It has not been carried by a Republican presidential candidate since 1988, it has not been seriously contested by Republicans since 1992, and it is reckoned to be part of the blue wall, referring to the group of states that voted for the Democratic presidential nominee in every election from 1992 to 2012. Additionally, it is the home state of Obama's vice president, Joe Biden, who served as Senator there from 1973 to 2009.
