Are you surprised?
We're talking about the same guy who said he is a Democrat, donates to Democrat campaigns, gives to the Clinton Foundation, wants universal healthcare, likes eminent domain, is not sure whether he is pro or anti-Second Amendment, can't get his story straight about whether a medical deferment or high draft number kept him out of the service, and decries foreign labor while having his clothing line made overseas.
If you don't like his position(s) today, just wait for tomorrow.
Try to keep up. They are threatening to block him from the debates. If they do that, there will be hell to pay.
