Something To Look Out For

Watching the footage of Donald Trump not nailing the election for his guy in Pennsylvania last weekend, I noticed how often when there are people in back of him while he's speaking, there is a minority person behind his left shoulder.

Couldn't find a still of the footage of him talking with a black woman with a big hat from last weekend but I saw the footage.

I first noticed that  from other footage of him talking to crowds during the campaign.   What's up with that?   Do they rent them from somewhere?
