http://en.wikipedia.org/wiki/Dead_cat_bounce"A dead cat bounce is a term used by traders in the finance industry to describe a pattern wherein a spectacular decline in the price of a stock is immediately followed by a moderate and temporary rise before resuming its downward movement, with the connotation that the rise was not an indication of improving circumstances in the fundamentals of the stock. It is derived from the notion that "even a dead cat will bounce if it falls from a great height"."
538.com conjectures that dead cat bounce might be McLoser's small poll gain last week.
http://www.fivethirtyeight.com/2008/10/todays-polls-1021.htmlAfter some incremental improvements by John McCain over the course of the past week, we are now looking once again a handful polls showing Barack Obama with a double-digit lead -- most dramatically his 14-point lead in the latest Pew poll. Obama also gained ground in the aggregate amongst the national tracking polls, which showed four Obama gains (Zogby, Gallup, Pew, IBD/TIPP), one McCain gain (Battleground), and three pushes (Rasmussen, Research 2000, ABC/Post).
What we may have witnessed is some sort of dead cat bounce for John McCain. One possibility is that, as more voters are taking advantage of early voting windows across the country, the pollsters are finding that some voters whom they considered "unlikely" voters have in fact turned out to vote. Zogby gives Obama a 21-point lead nationwide among people who have already voted, and SurveyUSA and Civitas peg his advantage among early voters in North Carolina at around 20 and 30 points, respectively.
