Bang!

In this case we have a person who would be a heartbeat away from the presidency with comparable "experience" to a person who wants the job now.

Sen. Obama hasn't had the responsibility of running anything in his professional life, let alone a town of 7,000 or a state of less than a million (Alaska ranks 47th of 50 in population). So, whether or not he would leave the US budget in tatters, based on no experience of ever having responsibility for a budget of any size, should be a concern. Having no public administration experience (Sen. Obama or Sen. Biden) is an issue, and was Sen. McCain not having any as well.

The last small-state governor (Arkansas, 33rd of 50) to become a president was a Democrat, and Democrats stated then state size was not an issue.

Personally, I think both parties based their VP choices in order to go after voters which they believed the primary candidate would not carry. That is unfortunate, because both went for vote-getting as opposed to establishing a team of leader-and-advisor. But, that's politics (sadly).
