Well if Hitlery becomes next POTUS Civil war is all but guaranteed. It still may happen before then depending upon the actions of our first radical Islamic POTUS B. Hussein in his last few years. 2nd Amendment I have no doubt he will try to destroy, he may even attempt to declare martial law to thwart elections and judging by the pieces of wuss bags in the Republican party he may just get away with it unless the people rise up.
I have been warning for the last few years that either a civil war or an outright revolt will come to break the USA apart. This is why I am not surprised by the gun sales over the last couple of years.
