Because her career options are getting limited. She is a democrat in a red state that is getting redder. She doesn't have much chance of keeping her seat. But a cabinet position looks great on a resume, and after the Trump administration she can enter the private sector more valuable than if she lost re-election. On our side, we get a good person qualified on energy issues and get to fill the seat with a republican. It is a win-win deal.

She knows the reason why and I doubt she'll fall for it.
