Poor Barack! What a twisted childhood the man must have had. Seems his mamma abandoned him after dragging him from pillow to post. Little wonder his reasoning is so screwed up. My prayers are with Obama!
The difference between Trump and Bernie's walls it that one would keep out undesirables while the other would keep in those that wish to escape the evils of a totalitarian state! The progressive left strongly opposes Trump's wall, but would be the first to support a Sander's wall, no matter what form it takes. Remember the Berlin wall? It was just the opposite of what Donald is purposing!!
