Over at Slate, Dave Weigel looks at Biden’s debate history. One nugget:
Biden’s job, in his Senate races, was to humiliate Republicans by pointing out how cruel their policies were, and how little they knew. Abortion and women’s safety issues, which he could never deploy against Palin, are the tools he knows best. When Biden meets Ryan tonight, it would be out of character if he didn’t try to mire him in a discussion of pro-life bills and “legitimate rape.” Plenty of pols use soft language when they have to discuss those issues. Biden doesn’t.
I suspect Ryan can handle this. He’ll be able to point out, for one thing, that Obama is sadly much more left-wing on abortion than Biden is.
