Ryan v. Biden will probably be the hottest ticket among the coming debates. Definitely worth watching.
Of course none of that means that Romney/Ryan will win anymore than it would Romney/Whoever. We are in a high-stakes game now in which democracy and ideas go out the window in favor of vicious attacks orchestrated by David Axelrod, et al. The Chicago crew will do anything possible to push the discussion away from the economy with as many distractions as possible. The compliant media can be trusted to be their more-than-willing executioners in this endeavor.
It will take a great deal of skill and hard work for Romney to keep the election focused on the issues. So far he has not been completely successful. But in this regard, putting Ryan by his side seems a particularly smart move. This guy usually has something to say and, for a politician, something remarkably substantive. The fight has been joined.
