It’s in keeping with the current GOP playbook. Check out this very short video of Trump literally shoving his way to the front of the Nato meeting photo op, saying “Move” -- not "Excuse me, please," to the rep from Montenegro. Then check out the look on his face and his body language. If this doesn’t tell you that we’ve got am embarrassingly grotesque buffoon representing the country, then you’re probably dumb enough to … vote for Trump.
