Time before election for supreme court nominations

Justice Ruth Bader Ginsberg died today, less than 2 months from the election and 4 months from the inauguration. About 5 years ago when Justice Scalia died, Senate Majority Leader McConnell announced that he would accept no nominee to replace him due to the proximity of the election, 9 months later.

Between WWII and today, there has only been one Supreme Court seat made open nearer to the election than Scalia's.  It came when Sherman Minton retired in Oct, 1956, just a month before the 1956 election, for health reasons.   President Eisenhower quickly made a recess nomination of William Brennan.    Eisenhower chose Brennan substantially because he was a liberal democrat, to assure acceptance by the opposing party.  Ike was extremely popular and won that election in a 57.4 to 42 % landslide, with only 73 electoral college votes going to his opponent.  Nevertheless, hearings were deferred until two months after the inauguration, at which point Brennan was confirmed by acclimation.  He would go on to be a very popular justice.

The columns here are the name of the new justice, the name of the justice replaced, the date the new seat became open, and how many months prior to the subsequent inauguration that opening occurred.
