Obama "bounce" short lived

Sarah Palin's nomination seems to have eliminated any Obama bounce even before the Republican convention takes place.

On the eve of the Republican convention, a new national poll suggests the race for the White House remains dead even.

A CNN/Opinion Research Corp. poll released Sunday night shows the Obama-Biden ticket leading the McCain-Palin ticket by one point, 49 percent to 48 percent, a statistical dead heat.

The survey was conducted Friday through Sunday, after both the conclusion of the Democratic convention and McCain’s selection of Alaska Governor Sarah Palin as his running mate.

A previous CNN poll, taken just one week earlier, suggested the race between Sens. McCain, R-Arizona, and Obama, D-Illinois, was tied at 47 percent each.

“The convention — and particularly Obama's speech — seems to be well-received. And the selection of Sarah Palin as the GOP running mate, also seems to be well-received. So why is the race still a virtual tie? Probably because the two events created equal and opposite bounces — assuming that either one created a bounce at all,” says CNN Polling Director Keating Holland. . . .

A Zogby poll shows McCain up by two points over Obama in a two person match up. It also shows him down by two points if Bob Barr and Nader are added in. Apparently Barr is taking a lot more votes from McCain and Nader is taking from Obama.
