The issue is ... Republican leadership has stated they will deny Obama from appointing a Supreme Court justice, no matter who he puts up. That grossly violates the Constitution which states it's their job to work with the president to fill such vacancies. That doesn't mean they have to confirm whomever he puts up, but it does mean at the very least, they have to consider whomever he nominates. If they had said nothing at all but gave every nominee a hearing and an up/down vote and rejected every single one because they don't want him appointing a justice, there would be no issue. Regrettably, they chose to go down the unprecedented road of unconstitutionally telling a president they will not be allowed to fulfill their own Constitutional obligations of appointing a replacement.
Not exactly.
This is what Senator McConnell said:
“The American people should have a voice in the selection of their next Supreme Court Justice," he said in a statement. "Therefore, this vacancy should not be filled until we have a new President.”
And, this is what then Senator Biden said in 1992:
Senate Republican leaders Monday seized on comments made by Vice President Joe Biden 24 years ago, when the then-senator from Delaware said the Senate should not consider a Supreme Court nominee during an election year.
"Once the political season is underway and it is, action on a Supreme Court nomination must be put off until after the election campaign is over," Biden said in June 1992 on the Senate floor, according to a C-SPAN recording of his remarks.
10 to 1 you didn't hold that against Biden and voted for the Obama/Biden ticket.
