Call it a "Secret Swiss Bank Account"
Ask "Why does any American need a Secret Swiss Bank Account?"
Ask "What kind of person bets against the American economy by holding foreign currency reserves in a Secret Swiss Bank Account?"
Ask "What are the loyalties of someone who has a Secret Swiss Bank Account? Is that person really 100% on the side of America?"
Point out that there are only two reasons someone has a Secret Swiss Bank Account... either they are hiding money they've gotten illegally or they are going to be hiding money they've gotten illegally.
Which one is Mitts' reason?
Those are all honest questions to be asking every day and Mitt needs to be asked them every day. He need to be made to answer them every day, because his answers will always expose him as a person out for himself and not America.
