Using Obama’s own words to determine who should appoint a new Justice

Since the news of the passing of Justice Antonin Scalia, legal and political commentators have discussed the possibility of an Obama recess appointment to the Court; the infrequency of election-year nominations to the Court (the last election-year nomination was in 1932, before Justice Scalia was born); the 1968 filibuster of Associate Justice Abe Fortas' nomination as Chief Justice; and various arguments for and against a vote on a nominee this year.
Those on the Left who would like to see an Obama nominee replace Justice Scalia point out that the people have spoken: they elected Obama in 2012, knowing that he could appoint more Justices to the Court. Conservatives may reply that the people also spoke in 2014, when they gave Republicans a solid majority control of the Senate.
