No country on history ever survived a 50/50 split intact and we are split in every way possible. It's only a matter of time. The smart thing would be officially splitting the country in two by agreement and relocating to one side or the other before it comes to a CW.
There better be a huge wall with armed guards. Within a few years millions of people in the lib country who thought they were good liberals are going to be at the wall demanding to be let in. When the ignorati in The Socialist States of America start demanding that all rich people "pay their fair share" to the "needy," all those rich white libs will discover that they are the new Evil Whitey. And since their guns will have been confiscated at creation, they will have a difficult time defending themselves from their new rulers.
