McCain's return to Washington was a victory lap of sorts after a bruising 16-month Republican presidential primary. He was visiting not only the White House he hopes to occupy but also the Republican National Committee headquarters that he essentially assumes control of now that he's the expected GOP nominee.
Obama's streak ends
With Tuesday's three wins – in Ohio, Texas, and Rhode Island – Clinton reversed an 11-contest losing streak. The seven weeks until the next major primary, in Pennsylvania on April 22, buy her ample time to raise money, sharpen attacks on her rival, and convince the elected officials and party leaders known as superdelegates that she is still a contender.
"She's back," Dr. Fowler says of Clinton. "This gives substance to her claim that she wins in populous states like California, and he wins in the little insignificant 'red' states. It just keeps things very confused."
The day offered Clinton a bright spot ahead of another challenging week. Wyoming's Democrats, who caucus on Saturday, vote in the club of red states Obama has dominated. In Mississippi, which votes March 11, more than half the Democratic primary voters are African-American.
Exit polls Tuesday show that nearly 6 in 10 late-deciding voters broke for Clinton, a sign that her increasingly aggressive tactics may be paying off.
