The Republicans have already announced that they are going to refuse to confirm (or even have a hearing to consider) anyone nominated by Obama to replace Antonin Scalia. Even before they hear who Obama is going to nominate. The Party of NO is nothing if not consistent.
The GOP claims that it is standard practice to not consider a Supreme Court appointment in the last year of a president’s term. So, how does that explain Anthony Kennedy, who was unanimously approved by a Democratic Senate in February during the final year of Ronald Reagan’s second term? Or the many other judges appointed in the last year of a president’s term.
