Palin's recent criticism of Fed's Chairman Bernanke plan to inject $600 billions into the US economy have gotten some notice. Her timing was impeccable.
Firstly, she was ahead of any other Anti-Obama politician to publicly voice opposition. A leader rather than a follower.
Secondly, she made this ahead of the G20 meeting, where Bernanke's, and thus Obama's as well, plan was panned. Her vocal opposition nicely planted a seed of her economic philosophy in international minds.
