Abel P. Upshur (1790-1844)

I confess that it seems to me exceedingly clear, that our Constitution is most worthless and tyrannical, if the usurpations of those who administer it, cannot be resisted by any means short of revolution.  I have always considered the reserved powers of the States, as the only real check upon the powers of the Federal Government; and I have always considered it, not only the right, but the imperious duty of the States, so to apply that check, as not to dissolve the Union.
