After discussing the pick of Paul Ryan as Mitt Romney's running mate and whether or not the columns at either the Wall Street Journal or the National Review might have pushed Romney into choosing Ryan or not, host John Roberts asks Bill Kristol about the likely attacks coming against Ryan from Democrats. And even Bill Kristol had to wonder if Republicans are going to be able to defend the tax cuts for the wealthy.

KRISTOL: I think taxes are the tougher attack ads. They combined, obviously, they're cutting Medicare. Why do they have to cut Medicare and gut education and do all these other horrible things when they insist on giving those tax cuts to the wealthy. But actually, if you look at polling, it's a pretty close call. People do know that entitlements have to be reformed. Even President Obama has said so. Hasn't done much about it. I think Republicans can pretty easily, honestly hold their own on that.

It's the tax cuts for the wealthy where Republicans have not done a particularly good job of defending it and I think you'll see the Democratic attacks really focus on that side of the equation.

ROBERTS: Steve Moore?

MOORE: Well, Bill is right. We know, we've known this for two years that the Democratic attack line would be we're going to cut entitlements and give tax cuts to the rich, because that's what the Democrats always do. Bill what I think is really exciting about having Paul on the ticket now is, who's better to defend those policies than Paul is and he knows this stuff better than anyone.
