Disobeying the highest law of the land is not a conservative principle.
Do not think for a minute that Abraham Lincoln fought the war of aggression to free the slaves per se.
The U.S. Constitution is the last defense against a tyrannical federal government against unalienable rights.
Lincoln was the worst ever offender of those rights. Worse than king George.
And now this government continually strips those rights from us.
Ron Paul sought to restore those very basic human rights.
Andrew Jackson was opposed to constitutional government.
You cited the very worst examples of presidents who violated the Constitution.
Will you now side with 0bama?
