These are the same LA Times pollsters who predicted that Gray Davis would survive recall..
and that Cruise Bustamonte had a 5 point lead over Arnold. When the only real poll that matters (the voting booth) was over, Davis was out of a job and Arnold had a 16 point lead over Bustamonte. Hey, what's a 21 point error between friends?
Sounds like their polling techniques need some work, like perhaps using a sample makeup that more accurately reflects the percentages of Republicans and Democrats in the population. The internals of their poll suggest they used a disproportionately high percentage of Democrats.
