Last–Minute Dueling in Wisconsin, Ohio and Texas Wait in the Wings

Nobody doubts that Barack Obama will win his home state of Hawaii, but Hillary Clinton's coming on strong in Wisconsin. Maybe Obama won't win ten in a row.

The real problem for McCain's campaign is how much to associate himself with the current President, George W. Bush. What's the best role for the current president in this year's campaign? We hear about growing uncertainties as time grows short in both parties.
