That’s a logical fallacy. Like em or hate em, PPP was very accurate during the 2010 election cycle.
Rasmussen is the gold standard in polling, and Rasmussen has Palin polling far worse than virtually every other GOP Candidate:
Why?
Is Rasmussen part of the conspiracy to get Palin?
here is the real lesson to the poll:
"...much can change in the next year-and-a-half."
"Its...worth noting that a great deal of caution must be taken in terms of interpreting individual results. It is far from clear which candidates will seek the Republican nomination and who ultimately will be nominated. At this point in 2008, everybody assumed the Democratic nominee would be Hillary Clinton, and Rudy Giuliani was leading the Republican field. One candidate on our list, Mike Pence, has already dropped out of the race. Other names will be tested in the coming weeks."
"In 2004, the last election with a presidential incumbent, Howard Dean was an early front-runner. Early polling also showed him as the strongest general election contender against President Bush. However, as soon as John Kerry became the front-runner, his numbers jumped to where Deans had been and Deans polling slipped. Its interesting to note that Kerry trailed Bush by three points on the night he became the front-runner, and he ended up losing the election by three percentage points. In 2008, Rasmussen tracking polls showed Obama leading McCain consistently by five or six points for the first month after Hillary Clinton bowed out of the race. Obama ended up winning by seven."
The lesson here is that the farther you are from election day, the less of indicator these polls become. Considering that the campaigns haven't even started yet, it doesn't make much sense to use these polls as an accurate predictor.
I will say this though. When the debates start, and the American public gets to see Sarah without the media whitewash, things are going to change in her favor, because she's going to dominate the debates.
Give her a chance to stand or fall on her own, and let the cards fall where they may.
