Donald Trump on Fox News today, after being asked about a potential Paul Ryan candidacy.
"I think his attack on Medicare makes him absolutely non-tenable.
I don't believe that he will run, number one, and I think that when he came out with a plan, attacking Medicare and Medicaid, I think that ends his presidential hopes -- at least, for a long period of time."
If you, like me, think Trump's political machinations are pure pander, then I'm not sure why he's attacking Ryan.
