Via her Facebook page, Sarah Palin endorsed former Fulton County Commission Chair and current Secretary of State, Karen Handel for the GOP nomination for governor. Handel has already secured the endorsement of Arizona governor Jan Brewer, and their stance on immigration is the same (I'd expect a Handel admin to pass a law similar to Arizona's here).
Handel's a movement conservative, but, while she's likely to get into the expected run-off, she faces a challenger (Insurance Commissioner John Oxendine) who has more money and name recognition, and who is making repeal of the state income tax an issue - to compete with Tennessee and Florida - neighbors without them. On most other issues, the two are indistinguishable, but, I bet a Handel administration would provide more interesting quotes than the bland Oxendine. Plus, she regularly appears on The Regular Guys radio show, so, she's got a sense of humour.
