Kos's take

Check out the following work over at Kos. He hits many of the points re: Palin poll numbers showing a 18 decrease over a number of days.

Update as of this morning (Sat 20th) the free fall continues at 24 point drop in 9 days. 40 favorable 47 unfavorable.

So we focused heavily on Palin, and make no mistake, it's exactly that intense
focus that has taken its toll on her numbers:
