My guess from that video is she will be fine with Perry and endorse him sooner than later. Wait for the latest polls. If Perry pushes out ahead of Romney or gets endorsed by people like Nikki Haley or Tim Pawlenty, Palin will too.
My thought too. I think she is seeing how he catches on and whether he gets a credible campaign up and running. If he is a disaster out of the gate, she might still jump in. But if, as expected, he gets a national campaign going and does decent in the polls, I fully expect her to endorse him and campaign with him. They are personal friends and, despite what some conservatives think, are pretty close ideologically.
Right now Perry is pulling away from Romney: http://www.intrade.com/?request_operation=main&request_type=action&checkHomePage=true
