Either it's a great bluff, or Paul Ryan will be announced as Mitt Romney's running mate in the morning. I blogged on it over at Post Partisan...pretty much what you would expect I would say, if you've been reading me on Veepstakes for the last several months.
I'm sure I'll be writing more soon, here or elsewhere, but not certain that I'll have anything tomorrow beyond "what mattered?", so consider this a comment thread for whatever y'all have on Ryan. I'll toss in a couple of links: here's Ezra Klein and here's Ryan Lizza, who both have exactly the kind of take on it that I'm dissenting from (although I agree with Lizza's take on Ryan himself and very much like his recent excellent profile of Ryan, and I certainly agree with Klein's view of the Ryan budget, especially the emphasis on the long-term budget).
