It’s totally appropriate. Liberals love the lip-service to the Constitution that Lincoln was good at, ignoring the principles of the Founders in truth, and he was concerned with their favorite issue - blacks. They love pushing the race card, and Lincoln is a favorite, as far as being the antithetical white guy who did everything for blacks, the most oppressed people ever.
"RUSH: Now, folks, I don't know how in the world Abraham Lincoln could be called a "bipartisan" by anybody. Abraham Lincoln was one of the most partisan presidents we've ever had, and you know what his bias was? His bias was the Constitution. He was biased toward the Constitution of the United States."
"We, the people, are the rightful masters of both congress and the courts - not to overthrow the constitution, but to overthrow men who pervert the constitution". ~~~ Abraham Lincoln
