That’s the conclusion of the Rasmussen study. Biden was judged the winner by almost exactly the margin separating the two presidential candidates at the moment. with partisans on both sides saying almost unanimously their guy or gal won. The only interesting stat: Palin comes out much higher than Biden on both the Very Favorable and Very Unfavorable front. Clearly she really has solidified the base, but she hasn’t converted many undecideds.
