Why is everyone picking on Michelle Obama and...?

people have realized that they can't really attack Obama on the issues (that would force them to look at Mccain's stance on things and that woud be disastrous for republicans) so they try to attack him on stupid things, they were so desperate that they even had to make up a story about his wife just to try and hurt him, and they still failed miserably, moreover sher is a woman so it is easier for men to pick on her.
