Until then, no president has ever been denied a confirmation hearing to fill a seat on the Supreme Court after nominating a replacement with 10 months remaining in their presidency.
But as I noted in my column, majority parties in the Senate have used a variety of procedural devices to thwart Supreme Court nominees; of the 34 failed nominations (not counting one who was withdrawn and resubmitted for technical reasons), only twelve received a direct vote, and five were withdrawn in the face of opposition. The rest were prevented from moving forward due to a variety of Senate procedures. Some of those involved a vote on the record to table the nomination, some did not (William Micou’s nomination by Millard Fillmore in 1853 died without any action by the Senate).
It Doesn't Matter That Garland Didn't Get a Hearing | National Review
The examples he gives...
Adams, 1828 - That came after the 1828 election, not 8 months before it, like with Obama in 2016.
Tyler, 1845 - Tyler was not elected president and of his nominees, some had hearings, some did not and one was even confirmed. That is not like what Republicans did with Obama in 2016 where they announced they would not hold a confirmation hearing for Obama no matter who he nominated and they announced that before he even picked Garland.
Fillmore, 1852 - Not elected president and his first nomination came in August, 1852, three months before the election. Not like Obama who announced his nomination in March of the election year.
Buchanan, 1861 - Buchanan's nomination was made 3 months after the 1860 election and 1 month before he was leaving office.
Hayes, 1881 - That came after the 1880 election, not 8 months before it, like with Obama in 2016. Not like Obama who announced his nomination in March of the election year.
Johnson, 1968 - That was not like Obama in 2016. Johnson's nomination came in June of 1968, was the result of a justice retiring to hand LBJ the replacement, and Johnson's nominee was given a confirmation hearing.
So no, there has never been a circumstance like Obama's where a president, elected to a 4 year term which includes nominating Supreme Court replacements, was flat out denied a confirmation hearing no matter who he nominated with 10 months (21% of his term) remaining in office. And not even a rightwing source like the National Review can spin it to make it appear like this was nothing new.
