Palin 47% Obama 47%: Turnaround & Why Marist Poll Is No Fluke
Poll Insider ^ | September 21, 2011 | Pollinsider
So, there has been much debate about a recent Marist Poll that shows Sarah Palin within 5% of Barack Obama and whether or not this is a fluke. For one thing, the numbers are actually closer to 47% Palin, 47% Obama, a tie. The Marist poll actually oversample Democrats compared to Republicans by 8 points, and oversamples both of them with Independents. (There has been a rise in Indy voters, but not to the tune of almost 40% of the population. Using historical trends, the anticipated 2012 Voter Turnout rate is 36% D, 36% R, 28% I. If your prefer the Rasmussen Partisan Preference it’s essentially a 3-way tie at 33.5% R, 33% D, and 33.5% I. In either scenario, you end up with a 47-47 tie.
The good news here for Palin again is that among the 6% Undecided, 67% are Independents, 20% are Republicans, and just 13% are Democrats. Undecideds usually tilt towards the challenger and in this case those undecideds are mostly Obama-Disapproving Independents followed by Republicans.
So, beyond reworking the numbers, how do we know that the poll is not a fluke? The easiest way to see it is not a fluke is because this surge only happened in Obama vs Palin, but not in Romney vs Obama. If it were merely growing discontent with Obama and a desire to elect a Republican, we would assume that all candidates would have surged equally or, at worst, half as much.
