Well, it's time for the Grand Ole Party - the party of Lincoln (this one I think), to gather together and attempt to revive the corpse of St Ronald and make Murica Grate - sort of like fingernails on a chalkboard, eh ??
One would think that convention organizers would have a bit of sensitivity and a rudimentary sense of historical perspective than to do this:
They've scrambled to remove the signs, but in cyberspace nothing ever goes away. Supposedly these "White" elevators were for delegate use -- Why not label them "Delegate Elevators?" but I digress.
Another twitter troll said that there were Red and Blue elevators also ("Oh say can you see, etc" - get it?) but I have yet to see pictures of their signs.
It really should be GRATE !!!
