Polygraphs are notoriously unreliable, so of course Kavanaugh should take one

The new FBI investigation into the allegations against Supreme Court nominee Brett Kavanaugh is mostly pointless. It seems unlikely that another week of digging will unearth the smoking gun evidence that Democrats are desperate to find. But anything besides that will never satisfy them. So, to prepare for the FBI's inconclusive results, they're finding other aspects of this circus to gripe about.

On Monday, Rep. Elijah Cummings, a Maryland Democrat, insisted Kavanaugh should take a lie detector test. After all, Cummings said, Ford took one. Sure, the test was paid for by her lawyers and the law firm was recommended to Ford by Sen. Dianne Feinstein's office. But other than those factors, it was a totally legitimate lie detector test. Of course, there is the very small issue that lie detector tests are not even close to being 100 percent accurate.

The American Psychological Association says:

Most psychologists agree that there is little evidence that polygraph tests can accurately detect lies.

Ford is a psychologist. You'd think she might have put a little less emphasis on her polygraph test.

The question is, why stop at a lie detector test? Especially if they're known not to be 100 percent accurate. How else can we learn the truth about Kavanaugh? He says he coaches youth basketball, for instance, but has anyone given him a written test on basketball rules and strategy? If not, the Judiciary Committee should be ashamed of itself. Such a test would give us a better idea whether he has what it takes to sit on the Supreme Court.

Yes, Kavanaugh has been a federal judge for 12 years, but has anyone actually seen his elementary school report cards? How do we know he even went to elementary school?

And another thing – according to Kavanaugh's calendar from 1982, he went to see "Rocky III" and "Grease II" in the same week. But what's the deeper meaning of that? Is he a Rocky kind of guy or a Grease kind of guy? And how would that impact his opinion on Supreme Court cases?

Sure, he might have a previous Senate confirmation under his belt, hours of new testimony, and written answers to 1,300 questions, but there is so much vital information we still don't know about Kavanaugh.
