It looks like the relentless dissing from Clinton, coupled with the rightwing media’s endless loop on Obama’s pastor is having is having their shared desired effect.

Democrat Barack Obama’s big national lead over Hillary Clinton has all but evaporated in the U.S. presidential race, and both Democrats trail Republican John McCain, according a Reuters/Zogby poll released on Wednesday.

The poll showed Obama had only a statistically insignificant lead of 47 percent to 44 percent over Clinton, down sharply from a 14 point edge he held over her in February when he was riding the tide of 10 straight victories…

The poll showed Arizona Sen. McCain, who has clinched the Republican presidential nomination, is benefiting from the lengthy campaign battle between Obama and Clinton, who are now battling to win Pennsylvania on April 22.

McCain leads 46 percent to 40 percent in a hypothetical matchup against Obama in the November presidential election, according to the poll.

That is a sharp turnaround from the Reuters/Zogby poll from last month, which showed in a head-to-head matchup that Obama would beat McCain 47 percent to 40 percent.

“The last couple of weeks have taken a toll on Obama and in a general election match-up, on both Democrats,” said pollster John Zogby.

Matched up against Clinton, McCain leads 48 percent to 40 percent, narrower than his 50 to 38 percent advantage over her in February.

Maybe Clinton is hoping McCain will ask her to be his vice president. Maybe she is just so eaten up with cut-throat ambition that she doesn’t care who she takes down on the way to Obama, including the entire Democratic party.

The poll was released Wednesday but it was taken March 13 and 14. What effect Obama’s speech had on the Elephant in the Room (racism) is still not known.
