After Fred Thompson and without having looked at her before, this is got to be the best choice McCain could have made, full stop. In some ways, she's even better than Thompson in my book (and no it's not the MILF factor). Look at her record as Gov of AK. Look at her stance on the 2nd Amendment. Look at her fiscal policies while running the largest state in the union. She's got more leadership experience right there then Obama could hope to fake on his resume.
Listen the list goes on, but don't get cocky. The election is still over 2 months off. Let's get out there and be counted.
