Latest presidential numbers

Is it a fluke? That one time in 20 when poll results are outside the margin of error?

The Gallup organization reports that Illinois Sen. Barack Obama has pulled even with presumed front-runner Sen. Hillary Clinton of New York for the Democratic presidential nomination. Gallup this week estimates Obama's support at 30 percent to Clinton's at 29 percent.

The poll also has former Vice President Al Gore, who isn't a declared candidate, running slightly ahead of former U.S. Sen. John Edwards.

No surprises on Gallup's Republican numbers, however. Former New York Mayor Rudy Giuliani still leads the crowded GOP field.
