I just saw Senator Paul on Fox News, where he made four substantive statements, one nonsensical, one innumerate, one economically illiterate, and one evasive to the point of dishonesty.
On the subject of collecting cellphone data without warrants, the host posed a hypothetical situation where a foreign terrorist is identified and we want to know which Americans he’s been talking to for the past six months. Paul’s answer: Get a warrant. The problem, of course, is that not even the US government, even newly armed with a warrant, is powerful enough to gather calling data that vanished into the ether six months ago. When the host pointed this out, Senator Paul ignored it.
On the subject of his tax plan, when presented with estimates that he’d be cutting taxes by 3% for the poor and by 13% for the rich, the senator could either have denied those numbers or defended them. Instead, he patiently explained that if you cut everyone’s taxes by 10%, then of course the rich will get bigger cuts (in absolute terms) than the poor. True, but to think that this was in any way relevant to the question requires a complete abandonment of all knowledge of arithmetic.
