Kerry is sincerely worried about the U.S. (as am I) if Bush gets re-elected.
In contrast, Bush's face looks like he doesn't have a "care in the world" -- which is because he is so clueless about his job and the world in general.
Regarding the "fem vote", the Bush campaign's success has been based on their ability to scare women, who are primarily concerned about safety. This is ironic given that Bush's invasion of Iraq (and lack of action in other places) has actually made the U.S. LESS SAFE.
P.S. - I noticed that the Bush Adminstration is asking for an additional $70 BILLION for Iraq and Afghanistan. Yep, we're burning about $4 BILLION A MONTH in Iraq, and it appears we will be there FOR YEARS AND YEARS.
