This firm was way off in 2018 (their final poll was R+3, whereas the actual result was +12). Similarly bad in 2020 (final poll was R+22, whereas the actual result was +33). You'd think a polling firm that only polls a single state would have figured out how to not be extremely bad at it by now!
Off by an average of 10 points - whew.
Though honestly, dialing up the GOP margin by 10 in this poll might prove to be somewhat close to the final result: (past 2 OK-GOV wins have been 14.8 and 12.1-point margins). And once again, it's possible that the Democratic candidate's final % is actually being more or less accurately reflected in the poll - they've just forgotten to give all the rest of the vote to the GOP candidate!
