real regions of the US (Oregon)

What's great is the map on the back of this postcard showing areas of the US that were “pro-slavery” and “open to slavery” which correspond very nicely with “Dumbfuckistan.” Also, lest the print be too small, let me reproduce below the quote printed by H.L. Mencken (1880-1956)

“As democracy is perfected, the office of President represents, more and more closely, the inner soul of the people. On some great and glorious day the plain folks of the land will reach their heart's desire at last and the White House will be adorned by a downright moron.”
