If you want to buy a T-Shirt or a coffee cup at Obama.com you have to give your 3 digit security code on the back of your credit card but if you want to donate you don't.
This is how Obama has been able to pull in $181 million dollars in donations, much of it from foreign donors.
The Obama campaign was caught not requiring the security code 4 years ago and it seems they are doing it again.
Course when your butt-buddy runs the DoJ you have nothing to worry about when you get caught breaking the law.
I went to his site myself and discovered they don't ask for that security code so they can make sure you own the card and are an American.
