Nobody took away Obama's power to make nominees.
Try to get a grip. How many of his nominees, judicial or otherwise, have actually been blocked? Not just opposed, successfully blocked. How many were approved? How many were approved without any cloture votes at all?
I have these numbers. Do you? In short, this is about specific nominees.
Also, a lot of the charts being passed around rely on the reader not having a clear idea on the difference between "subjected to a cloture vote" and "blocked."
