(If asked about why you signed NAFTA and sent thousands of jobs and billions of dollars to Mexico...) "I feel your pain, but Americans are can-do people. We never give up, and we persevere and overcome obstacles and challenges... blah blah blah."
(If asked the difference between your outright dismissal and decrying of allegations of perjury, fraud, conspiracy and evidence tampering against you, your wife and several in your administration as 'baseless' and your insistance that allegations of possible other allegations of appearances of impropriety by staffers of your political opponents be investigated by the Justice Department, The FEC and a special prosecutor...)
