What about first spouses?
Of course, we must focus on the actual candidates, but what about their spouses?
Obviously, Clinton has Bill.  It's unprecented for a former president to be the spouse of a new president.  Not sure what I think of that...
I don't have a particularly favorable opinion of McCain's wife.  She seems rather secretive and unpleasant.  I'm not sure she would be a good public asset for McCain if he was elected.
Obama's wife is ok.  She would eventually get the hang of public speaking, I think, but she would still look rather dull compared to her husband's excellent public speaking abilities.
I know that Edwards is out of the race, but I am most impressed with his wife.  There were times early in the campaign when I thought she should be running instead of him.
