His foreign policy knowledge, easy confidence on the stump, and compelling personal story were all obvious Biden attributes, but his prime advantage was pretty clearly that no one has as many white family members as Joe Biden. Mama Bidens, baby Bidens, handsome Bidens, gramma Bidens. As Obama finished his speech, they just kept coming, waves and waves of them, till the whole stage was filled with stereotypically wholesome Bidens. Neat trick.
