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, with [sic] the statistical margin of error.
The survey was conducted Friday through Sunday, after both the conclusion of the Democratic convention and Sen. John McCain’s selection of Alaska Gov. Sarah Palin as his running mate.
A previous CNN poll, taken just one week earlier, suggested the race between McCain, R-Arizona, and Sen. Barack 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.
