Sessions can see him in his peripheral, Biden starts moving back the very frame Sessions opens up his hand, a universal gesture to stop, and look at the way he looks at Biden afterwards... watch again... it shouldn't be that hard to notice... But a question I would like to ask you is, do you not like Sessions?
The initial swat comes right as Biden is about to make contact with her shoulder, that is when he reacts, the exact point he notices Biden hand... Look closely at .25 speed and notice where Biden's hand is and the point when sessions moves his hand back then reacts, this is actually pretty clear to notice that Biden retreated because of the action and that action was intentional.
Great news, thanks for the update, I am from Wisconsin and didn't know what the numbers were at yet. With that said, I will say Trump winning Wis in 16 was not expected by anyone here, this is definitely a good sign of what is to come in Nov.
climate change was just a flash in the pan, race was the fire.
