anonymous jew,
Reid did not eliminate the filibuster for SCOTUS nominations. That was done by Republican Mitch McConnell.
So the list should be:
3. Who eliminated the filibuster for judicial nominations besides SCOTUS? Democrat Harry Reid
3.5 Who eliminated the filibuster for SCOTUS nominations? Republican Mitch McConnell
4. How many Trump nominated Supreme Court Justices were approved with less than 60 votes because Mitch eliminated the filibuster? Three
It is not important the number of times that the filibuster was used. Nor the number of times it wasn’t used because the bill was withdrawn before being filibustered.
What is important is what it was used for.
