if 50 states all secede, would that leave just Washington dc and porta rica in the USA?
Well, I think the Union would collapse well before the 50th state seceeded. In any event, in addition to porta rica* (sic), the U.S. has other insular territories as well, including Guam, American Somoa, Northern Mariana Islands and the U.S. Virgin Islands (which, I should point out, is a beautiful place).
