I have not followed enough to form an educated opinion to be honest ~ I hate American style politics for the most part because they spend more time focusing on whats 'have not done' verses what they would do ... and sadly it has been rolling over into Canadian politics as well these past few decades!

That said I like Barack Obama as a speaker ~ he is very powerful and truly seems to mean what he says verses 'reading from a speech' like many others who stumble over their words and from what I have seen of Mitt I do not trust him ~ he gives off that air of 'corporate greed' where I would worry that policies made under him would put big business ahead of the people again or that like Bush and others before him they would willing go to war for PROFIT over oil and so forth in other countries while 'claiming' it was for the benefit of National Security!

But I admit that is an uneducated opinion based on clips from 'news' that make it over the boarder!
