It’s all about power.
Donald Trump is not the first president who has railed against rampant illegal immigration. He is not the first to support the building of a wall/barricade along the Mexican border. It is not just a Donald Trump issue. It’s an historical American issue supported by both sides of the aisle over the years. Until now.
In 2006, the Secure Fence Act was passed by congress allowing for the construction of nearly 700 miles of border barriers, i.e., walls, fences. The vote passed in the senate, 80-19. Could that happen today? Among those who voted for the bill were Senators Barack Obama, Hillary Clinton and Chuck Schumer. Anyone can check Youtube and find several examples of those notables on the left who, 10-20 years ago, made speeches in support of a border barrier.
According to the Department of Homeland Security, half of the 2000 mile Mexican border is already protected from mass migration due to terrain. With roughly 700 miles complete, that still leaves 300 or more miles of open borders that need fixing or else the caravans will continue and illegal immigrants will never cease swarming into our country.
