From Josh Marshall, this report:
The Romney campaign seems to have leaked the fact that Mitt Romney asked Chris Christie to appear with him at a rally Saturday night in Morrisville, PA. But Christie declined. This is being portrayed in GOP circles as another example of Christie’s compromised allegiance to the GOP ticket.
Marshall quite rightly points out the "shitstorm" that Christie would have faced by leaving New Jersey in the middle of a crisis to go campaign for Romney.
It’s frankly such a crazy request that it shows just how deeply Romney’s been stung by Christie’s praise of President Obama.
I think it's more of an indication that Romney simple can't conceive of any reality that doesn't have him as its center.
(Christie's office is saying he was never invited.)
