I don’t really believe any of the official stories, and I will be very surprised if, as she says, she’s not running for president but will instead campaign for Trump. (If I was thinking of running, that’s what I would tell Trump. She also probably wants to get the stench of Kavanaugh off her.)
Two weeks ago, when Trump spoke at the UN, I saw lots of comments from Trumpworld that she’d done the unthinkable: She overshadowed Trump at the event. Insiders predicted then she’d be gone.

Nikki is a politician first and a diplomat……a very poor diplomat…….second.
She saw the pending November doom of the Republican Party and jumped ship before she lost everything.
