It's Independence Day, so many Americans are reflecting on the year 1776, when this nation was born. But today's rancorous political divisions are also a reminder of 1861, when President Lincoln explained in a Fourth of July speech why war was necessary to crush that period's "states' rights" movement.
More than 150 years later, another crew of states'-righters are challenging a president. They're not threatening to secede, but are vowing to ignore a law passed by Congress and recently deemed constitutional by the U.S. Supreme Court — the Affordable Care Act, which they have derisively dubbed Obamacare.
The most vocal of the law's critics tend to be governors of some of the same rebellious Southern states Lincoln named in his 1861 address to Congress, when he announced that the functions of the federal government had been "generally suspended within the several states of South Carolina, Georgia, Alabama, Mississippi, Louisiana, and Florida."
