Politico calls New Hampshire Gov. Chris Sununu "Washington's Favorite Republican." That means he is the latest avatar of the Bush-McCain-Romney-Ryan-Bush-Cheney wing of the Republican Party. Politico does Sununu no favors by so denominating him.
In an open primary on a good day with a tailwind, that status has to be good for at least 1% of the votes cast nationally, In other words, your basic snowflake in hell has better survival odds than Sununu has in the GOP's primary process.
Put a fork in him, he's done before he starts. In fact you could call him "precooked."
