There is no die-hard Republican out there still wondering about McCain's choice here. They will all be sold after this. The only question they will be asking right now is why she is the bottom of the ticket instead of the top.
Of course, this may change once the initial euphoria wears off and we see her in unscripted settings. Or if more issues about her past or her more radical views come out.
But maybe not...
Now, will it flip many undecideds? I don't know. But it seems more likely today than it did yesterday.
