Todd & Specs,
Did y'all listen to the interview? Laura specifically sided with Rand w/regard to his foreign policy, and even talked about how she's been taking flack from "neocons" (her word) about not wanting to go head to head with Russia.
My take on the Fox News segment was that Laura was actually trying to help Rand (and herself) by showing he isn't the only guy out there in the Republican field seeking a rational role for America on the world stage. Though it could be interpreted that way, I don't think she was trying to give Donald credit for being the first to have the idea about a humble foreign policy.
She's put a lot at stake in siding with Rand here, and I applaud her for it.
