For weeks, Democrats have been trying to call voters' attention to the financial dealings of Mitt Romney, the presumptive Republican presidential nominee.
Supporters of President Obama, the Democratic Party's candidate, have been suggesting that Romney has exploited tax shelters and offshore accounts to build and protect his wealth in ways that average taxpayers would never be able to do.
They are demanding Romney release many years of tax returns.
As Mitt Romney has faced questions about his investments and tax returns, the likely Republican presidential nominee has responded with two words of explanation: blind trust.
Romney keeps most of his wealth in a blind trust designed to prevent him from knowing exactly where his money is and what it's doing. It's a long tradition for presidents and candidates, though anyone can set one up if he wants to.
But it turns out that not all blind trusts are equally blind. Some are cast into complete and utter darkness. Others are more nearsighted.

One of the first times photographer James Startt recalls seeing Lance Armstrong was during the 1992 Olympic trials as the two rounded a corner together. Startt, an avid cyclist, says he only came close to Armstrong once during the tryouts.
Engineers say technologies like spray-on clothing and 3D-printed shoes could help future Olympians break records. The Institution of Mechanical Engineers' Philippa Oldham discusses how technology impacts sporting performance and why engineers should work closely with regulators.
How does blood doping boost performance in events like the Tour de France? Do anabolic steroids help the world's fastest man run faster? In his book, Run, Swim, Throw, Cheat , Chris Cooper discusses how these banned drugs work, or don't — and how they are detected.
Florida's Aquarius Reef Base is the only working undersea lab left today. But now that federal funds have dried up, it may be forced to surface. Oceanographer Sylvia Earle joins Science Friday from inside Aquarius, 60 feet underwater, to talk about sponges, corals and other life she's observed on the reef.
ERIC MCCORMACK: (As Doctor Daniel Pierce) In this class, we're interested in what goes on in the brain. And if we were to put someone in an FMRI machine and watch what happens when they make up a lie, we'd see their dorsolateral prefrontal cortex light up like a Christmas tree...
MCCORMACK: (As Doctor Daniel Pierce) ...because we use our brains when we lie. We use our brains when we're being lied to. But can the brain ever lie to itself?
