(Bloomberg Businessweek) -- A new CNN poll out this morning shows Joe Biden with a commanding lead over the rest of the Democratic field. With 29% support, Biden is lapping his nearest rivals, Bernie Sanders (15%) and Elizabeth Warren (14%). Kamala Harris, whose attack on Biden’s busing record vaulted her into the top tier after the Miami debate, has plunged to 5%.
