The Mormon church has historically flip flopped at the slightest indication that the trend is not in their favour. This has gone on for 150 years. They sense that Mitt is not going to be able to produce for them and that he may even hurt their image.
This is as Mormon as you can get and Mitt has learned his Sunday lessons well. Unfortunately for Mitt, it is Mormon to dismiss your own for the sake of the whole. He's been shunned.
