"Yeah, Oklahoma is probably tired of frackquakes and wants someone who will actually oppose the shit rather than cave to whoever offers him/her the most money."
Inasmuch as we are tired of the earthquakes caused by the destabilization of the earth caused by the disposal of waste produced by hydraulic fracturing (fracking by what literally everyone calls it), you are correct. It's gotten to the point where we've surpassed California as the state with the most earthquakes per year. There's a commercial promoting fracking saying it is safe for the environment because it doesn't emit any gasses into the atmosphere. Right, it just has caused an entire state to have to live with earthquakes for over 5 years now despite the fact that this isn't a part of the earth that should experience earthquakes, let alone this frequently.
However, fracking has little to absolutely nothing to do with why the Democrats here chose Bernie. They chose Bernie because of the last name of Clinton. There just really isn't any sort of trust for her here. The Oklahoma City area is the only major area that favored Clinton over Sanders, and it's more closely tied to the South than any other part of the state (people like to consider Oklahoma part of the South, but Oklahoma for the most part hates being mentioned as part of the South, at least from what I hear around the Tulsa area, everyone assumes we're actually part of the Midwest). Another thing about the Democratic primary is that the state Democratic party as of November said that Independents will be allowed to vote in their primaries for the next few years, and since Bernie is more favored by the Independents and those make up actually a decent portion of the state, I assume some of that support gave Bernie a boost. I've long predicted a Bernie win here
