I don't know, I mean I can understand your desire to want to change your mother's mind but do you really think that anything you do or say will change her mind? There comes a time when you have to accept that people you are close to will have different political opinions.

I think do what you can to show her why she should vote for Obama but honestly, if she is dead set on voting McCain I doubt there is anything that you will be able to do to convince her otherwise.
