BIDEN - OF SO MANY ETHNICITIES - IS IRL OF BRITISH AND IRISH ANCESTRY. HIS NAME COMES FROM A PATERNAL ANCESTOR WHO EMIGRATED FROM SUSSEX, ENGLAND TO MARYLAND. HE'S OPENLY ANTI-BRITISH, AND IT'S WIDELY KNOWN (AS WAS OBAMA FOR SIMILAR REASONS). IT'S WHY HE'S NOT AT CORONATION. ALSO EXPLAINS FAILURE TO NEGOTIATE IN GOOD FAITH RE: NORTHERN IRELAND ON HIS RECENT TRIP. THIS IS DUE IN LARGE PART TO HIS IRISH MOTHER,WHO WAS RABIDLY ANTI-BRITISH, AND RAISED HIM TO BE. YET HE'S AT LEAST 3/8 ENGLISH IN ANCESTRY.
