Let's break it down by age:
She was a mom raising her kids at home, from age 18 to 32.
Palin was part-time mayor of a town of 900 people, from age 32 to 38.
She worked for an oil company lobby group from age 38 to 42.
At 42 she became governor.
She's 44 now.
And she wants to be a heartbeat away from staring down lifetime power machines like Putin and ahmedijahad. I just don't see her experience in economy, world affairs, etc. She doesn't have the network of relationships that clinton, mccain, and biden have- and that Obama has worked to build fairly decent in the last 2 years as well.
She doesn't have those world connections, relationships, and experience to help her judgment. If ANYONE is learning 'on the job' it's certianly her.
