and what was the unique aspect for obama?
that he was the first black who ran for president who actually had a chance at winning and ..he was unique in that he won the primaries and beat a very formidable opponent....
but what you so conveniently forgot was that Hillary initially had the black vote locked up...blacks initially did not support Obama....not to mention Hillary had the nomination sewn up after destroying Obama on Super Tuesday....she began to lose support after she and her staff coasted after Super Tuesday while Obama kept campaigning hard and ran off TEN straight primary wins.....
also remember that Bill Clinton and Hillary herself made some questionable comments about blacks and Obama..and that helped turn the tide against her
