Summarizing, Fallin has a 38-point lead over Brogdon (who apparently can't draw more voters than undecideds), Edmondson leads by 16 over Askins.
Poll taken July 16-21. Margin of error ranges from 3.5 to 5.3 percent.
I think we can safely say that Brogdon is dead meat.
However, I've received (and others, no doubt) robocalls about Barry Switzer's endorsement of Askins. So the Democratic race may be closer than indicated, especially if Askins gets a bunch of the undecideds and the poll's error margin works in her favor.
The Sooner poll has been the most accurate political polling company lately. It will be interesting to se how close they are this time.
