If you really want a case study in how wacky poll results can
be, check out the latest contradictory
generic ballot polls. Pew, USA
Today/Gallup and ABC News/Washington
Post have the Democratic lead among likely voters in the 4-7
point range, while Newsweek and
Time have it in the 15-16 point range. The
polls not only contradict each other as far as the numbers are
concerned, but also in terms of their trajectory. The Pew
poll "finds voting intentions shifting in the direction of
Republican congressional candidates in the final days of the 2006
midterm campaign," while Newsweeksays
"Republican candidates are falling further behind Democratic
rivals."
