Here are a few things the framers did not know about: World War II. DNA. Sexting. Airplanes. The atom. Television. Medicare. Collateralized debt obligations. The germ theory of disease. Miniskirts. The internal combustion engine. Computers. Antibiotics. Lady Gaga.That's right, folks. Thomas Jefferson, James Madison and their contemporaries had never heard of third-rate Madonna-wannabe Lady Gaga, so naturally their opinions on limited government should be discarded. This is beyond an insult to the intelligence.
The US Constitution was certainly not dropped down from heaven, is far from perfect, and does not have the power to enforce itself - that requires vigilance from the people of the US. Nevertheless, it has a mechanism for amendment, and it does stipulate limits on the federal government. When these limits are overrun, liberty is threatened and the danger of tyranny grows. The fundamental danger to the United States comes not from the Constitution, but from those who violate it.
