From a reader:

Jonah,
One wonders whether R2000 polling data has ever been used to back up claims of voter fraud, etc. I don’t have time to do much checking, but happened to stumble across this link with a breakdown of various polls in the Brown/Coakley election. The spread is hysterical…
Have a great day.

Here’s the spread in question:
