Senate Leader Mitch McConnell blocked President Obama's "pick" on the grounds that it was an election year, although it was some months until the election. The same Mitch McConnell has stated, almost within minutes of the announcement of Justice Ginsberg's death, that he will bring Donald Trump's candidate to the vote immediately. A small number – four, so far, I think –of Republican senators have said that they will vote against a new appointee at this time. One of the four has a habit of changing her mind.
