I think Arnold would be a good VP candidate for 2008, should he lose re-election (the Consitution appears to me to only mandate that the President must be a citizen, not the VP, which until recently was not regarded as an important position)....
the VP has to have the requirements as the President because he has to be able to assume the presidency.
I'm thinking 73-75 would be the only ones to get my yes vote.
