"The choice also says a lot about McCain. First, that he is a bit desperate. McCain likely thought it would be difficult to make a splash with a conventional Republican sidekick. Changing the subject from Thursday's Obama-thon would be difficult with Mit Romney or Kay Bailey Hutchinson (who would have been an awful choice anyway) by his side. The choice of Palin certainly gives us all something new to talk about. And she is fresh, smart (as far as I can tell from a brief time studying her), enthusiastic and energetic. But it is a bit of a political Hail Mary pass.
Second, that he is one arrogant SOB. McCain is essentially telling the world that he doesn't really need a Vice President.
McCain is essentially telling the world that he doesn't really need a Vice President. It is hard to imagine Palin playing the same sort of role that modern Vice Presidents like Gore, Bush, Cheney, or Mondale played. Rather, the Office would seem poised to return to the "proverbial warm bucket of piss" category. McCain has thus made a purely political play without regard for the governance concerns. And how could he really have a good idea of how she would govern? My understanding is that he only met with her once before choosing her," - Shannen Coffin, NRO.
