Polls Show Obama Could Sweep Again Today

Barack Obama has won all 5 contests since Super Tuesday and polls show he could win all three being held today as well. The latest polls show Obama with a 22 point lead in Maryland and a 17 point lead in Virginia. While I haven’t seen any polls in DC, the huge majority of black voters (who have voted overwhelmingly for Obama thus far) should make the outcome there a foregone conclusion.

How many defeats can the Clinton campaign withstand before people start seeing Obama as the obvious choice for the Dem. nomination?
