CNN/USA Today/Gallup Presidential Poll

"If Massachusetts Senator John Kerry were the Democratic Party's candidate
and George W. Bush were the Republican Party's candidate, who would you be
more likely to vote for: John Kerry, the Democrat, or George W. Bush, the
Republican?" If undecided: "As of today, do you lean more toward John Kerry,
the Democrat, or Bush, the Republican?"

February 16/17 Bush 43% Kerry 55%
March 26-28 Bush 51% Kerry 47%

That's a 16 point swing in 6 weeks. Looks like Bush has got the big "Mo".
