The selection of Sarah Palin as McCain's VP is by any estimate a very interesting pick.  Her pro-life Catholic roots should help McCain with blue collar Catholic voters generally.  I'm starting to feel that this election comes down to who wins Colorado and New Mexico.  Perhaps McCain flips New Hampshire.  Certainly McCain must "hold serve" on more states than Obama to stay even and that puts more pressure on him.  If Obama gets momentum and starts flipping states like Ohio, Virginia, Nevada or Florida its all over.  It is less likely that McCain flips Democratic states like Pennsylvania or Michigan but is possible.

So I think it comes down to Colorado and New Mexico.  Can two Westerners make these GOP states?  And can Palin's Catholic roots help with hispanic voters in New Mexico?  We'll see.
