Being a foreigner to the US and your politics, but ... abiding by the no boundary rule:
Osama - charismatic, has youth on his side, and is very persuasive,
but ... generally I find women to be more practical, so I will probably listen to a woman first. Then I guess the first woman president should be a past first woman?!
Now, not being really up to speed with either of their policies and what they mean for the public in the US and as a consequence Australia, I defer to your comments.
