Sadly, I think you're right DT. I hate when people play the race card at a whim, BUT with this group of whackos, the more they beat this dead horse, the more I think it's exactly that. They don't want to say it, but it's there.
If it were an uproar on a policy or any legitimate "issue" I wouldn't think so, but this is simply baseless and unecessary.
They have a right to their opinion, and they won't go away soon. On the up side, they are a very small minority, as a whole, thankfully.
I am hoping the security around the President is "extra" vigilant.
