Can you name which of the delegated powers in the U.S. Constitution allow the president to invade his own country, mass murder his own American citizens, and bomb, burn and plunder their cities? Can you explain how such acts would be consistent with protecting the constitutional liberties of those unfortunate citizens? If you think you can, then congratulations, you are a “Lincoln Scholar.” If not, do not despair. You are in decent company, including the five living past presidents as of 1861, namely, Martin Van Buren, John Tyler, Millard Fillmore, Franklin Pierce, and James Buchanan.
