Going backward from Ras/POR's latest polls:
WA-Sen 49-47 Murray - almost exact
OH-Gov 48-44 Kasigh - actual 49.4-46.7 - almost exact
NV-Sen 48-45 Angle - every public poll got this wrong
WV-Sen 50-46 Manchin - nearly identical to PPP result, both slightly underestimated Manchin
CO-Sen 50-46 Buck - every public poll in the final week had Buck leading
CO-Gov 47-44-6 Hickenlooper - every public poll overestimated Tancredo vs Maes, and many votes were cast well before the poll was even taken, likely favoring Maes
IL-Sen 46-42 Kirk - actual 48.2-46.3, right on target
IL-Gov 44-38 Brady - same result as every other public poll, all underestimated the final result of 46.1-46.6 Quinn
CT-Gov 48-46 Foley - very close to actual result of 49.0-49.5. No poll showed Malloy winning, the only one showing a tie had 10% undecided/3rd party.
CT-Sen 53-46 Blumenthal - actual 54-43, right on target
How much more do you need to see? In every single case, Rasmussen's polling was either exact, extremely close, or a bit off but in agreement with every other public poll.
1. I’m comparing Rasmussen to actual results - not to PPP
2. You selectively omitted many races which don’t support your case
3. Many of your numbers are just plain wrong. see this chart:

I stand by my comment.
