That was speedy. Sen. Ted Cruz pipes up, and doesn't think the sitting president should be appointing anyone at all to the Supreme Court to replace Antonin Scalia.
Other conservative voices are also piping up with this idea in the media.
To be clear, there's no constitutional provision that supposes a current president with a year left in his term of office should simply not appoint anyone for that year, leaving the Supreme Court with 8 justices until some other president takes the oath of office. The Constitution is clear; Obama gets to name the next justice of the Supreme Court.
