With Romney out, Paul Ryan says he'll stay neutral in 2016

That apparently includes even fellow Wisconsinite Scott Walker, who is considering a presidential campaign.

“Had Mitt jumped in, I think that would have changed circumstances,” Ryan said. “But since I’m the chair of this trust…that requires my neutrality. But, look, let me say Scott Walker’s a great governor. He’s a good friend of mine. He’s a reform governor. He’s done some amazing things.”
