I don't see how any of that stops the Republicans, who would have been in power in OK the entire time, from saying, "B- b- but, it's the EPA and the Department of Energy's fault! And if Barack Hussein Obama hadn't passed all those job-killing environmental regulations from 2009 to 2017, none of this would have happened!"
I could see Oklahoma electing statewide democrats before TX, as TX seems to have a more diverse economy (not just oil/NG) at this point. Obama's Presidency would be a tough one to overcome. Of course, if a GOP President is elected for 8 years and oil stays at $25/barrel, barring a recession or major war, said President would be quite popular.
