Either these people truly are the dumbest damn people on the planet, mentally handicapped or they're leaving these borders wide open for a purpose.
There is an agenda.
Think about it, whether republican or democrat, the borders have remained porous for decades.
Violence rages on and spills over into our country year after year whether Bush, Clinton, Bush, O-bozo.
Over the last decade, approx. 30,000 people have been killed down there.
Motivated by parochial self-interest, the pro-mass immigration, open borders, amnesty advocates have formed a powerful coalition including the U.S. Chamber of Commerce, labor union leaders, the Catholic Church, ethnic and racial groups, “moderate” Republicans, and the Democrat Party. The common thread that unites these groups is power, money, and the prospect of increased constituencies, even at the expense of our long-term national interests and survival.
