Is America sliding toward autocratic rule? This is the essential question of Barack Obama’s presidency. Mr. Obama vowed to “fundamentally transform” the United States. Despite his incompetence and economic failure, the president is making good on his central promise: the destruction of our constitutional republic. He is trying - piece by painful piece - to reverse the legacy of the Founding Fathers. Conservatives have underestimated him at their peril. For Mr. Obama is not simply an inept, liberal president in the mold of Jimmy Carter. He is an ideological revolutionary who seeks to sweep away traditional America.

The American war of independence did not just overthrow British imperial domination. The Founders forged something almost unique in history: a nation devoted to individual liberty, Christian civilization and federalism. The rule of men was replaced bythe rule of law. The linchpin was constitutional government based on the separation of powers and checks and balances. The American system is entirely predicated on the Constitution. Once the Constitution becomes meaningless or just an inconvenient piece of paper, the American experiment is over. The republic is dead.

This is what’s at stake. Mr. Obama is acting like an arbitrary tyrant.
