The point is that the bill was the only one that made it to the SC Leg floor.
Pinckney didn’t vote in favor of having the flag on the Capitol grounds, he voted for removing it from the Capitol roof.
The original blog post seems rather... ignunt.
To suggest it here makes the suggester seem ignunt, too.
Are you absolutely certain that the Senator didn't understand that the bill required “permanent placement” of the flag at the Confederate Memorial and that it would have the force of law?
If you are certain, could we see your data?
