On Potomac Primary Day, Clinton Focuses on Later Contests

Rudy Giuliani figured he could lie low until the Florida primary, but John McCain's momentum put an end to Giuliani's campaign. If Barack Obama wins today -- as expected -- in Virginia, Maryland and Washington, DC, that will mean eight losses in a row for Hillary Clinton, with Obama leading next week in Hawaii and Wisconsin. Now Hillary Clinton is counting on Ohio and Texas, which don't vote until April. Susan Milligan, who covers presidential politics for the Boston Globe, says that's changed what both candidates are saying and could effect super-delegates.
