Cooking with AP: Polls Radically Change Party Mix to Fabricate an Obama Trend

The data is included in the link above. Here's the just of the story:

After correcting for differences in the samples, almost all of Obama's double-digit pickup disappears, leaving McCain with four- and three-point leads without and with leaners, respectively. Even if one argues that the first poll showed a too-small gap between the two parties in the number of people sampled, substituting the 5-point difference Gallup identified shortly after the GOP convention would still leave McCain with a slight lead.
Either AP isn't supervising its GfK cooks properly, or it's directing them to poison discussions of presidential race, while hoping that no one notices the rancid product it is clearly producing.
AP waitress -- er, reporter -- Liz Sidoti brought out the new poll's results for our consumption yesterday with this exultant intro:
Barack Obama has surged to a seven-point lead over John McCain one month before the presidential election, lifted by voters who think the Democrat is better suited to lead the nation through its sudden financial crisis, according to an Associated Press-GfK poll that underscores the mounting concerns of some McCain backers.
Likely voters now back Obama 48-41 percent over McCain, a dramatic shift from an AP-GfK survey that gave the Republican a slight edge nearly three weeks ago, before Wall Street collapsed and sent ripples across worldwide markets.
As you can see above, her celebration is founded on fabrication; thus, her "explanations" are deep-fried in deception.
Just because AP, GfK, and Sidoti are serving us this rotten recipe doesn't mean that readers have to swallow it. So don't.
