Even if they are shown to the public, I think it's going to be a big dud. And I hope folks (I'm looking at you Rachel Maddow) don't work themselves up expecting this to be the bombshell.

Tax returns do not detail individual items. They aggregate numbers. So let's say he did get a $1 billion dollar loan from Vladimir Putin, the source of the loan would not appear on the forms. Just the interest paid on it (aggregated together with all the other interest paid)

Is there going to be illegal activity illustrated in these documents that he had to file with the IRS? Doubt it.

I think all we'll see is that he used the tax code to his advantage to pay as little tax as possible. Big surprise.
