Good luck with that.
Whining about how OPEC has "a monopoly" is just silly; American anti-monopoly laws don't have much effect on other countries for obvious reasons, and there's just no way that yelling about "monopoly" will affect states that have nationalized their oil production. The reaction to the accusation of monopoly will be "yeah? And? So?" Or some variation thereof.
Between this and the gas tax holiday, I really get the sense that Hillary knows that Wright isn't a winning issue, and wants to ride the gas price issue all the way to Denver. The problem is that she's being dumb about it; instead of using it as a springboard for interesting renewable energy proposals, she's pulling out proposals that every expert in the country says will have no positive effect whatsoever. She's just as tired as Obama, but it's coming out in a different way; her actual ideas are slipping, instead of her delivery.
Or maybe she's just desperate. Either way.
