By Nolan Lewallen, The Stream - Article 4 Section 4 of the U.S. Constitution states: “The United States shall guarantee to every State in this Union a republican form of government, and shall protect each of them against invasion.” The powers that be on the Left can quote that, and yet we’ve witnessed an all-out invasion at our southern border for nearly two and a half years. They have invaded from more than 160 countries, and a recent Pew Research poll found that 63% of them are coming from countries other than Mexico and the Northern Triangle.
