So your excuse for Trump to hide his tax returns is because they're too corrupt??
No, but he probably took every tax deduction available to him, didn't contribute much to charity, or something like that. Look at the slack Biden and Al Gore took for only donating a few hundred dollars to charity, and they had the MSM on their side.
If his taxes were corrupt, you can bet your last dollar the IRS would have found it. Anybody here that thinks they can find something the IRS hasn't is full of themselves. Like I said, the only reason the left wants his tax returns is to have something to bash the guy with. It would make no sense for him to give the left that ability.
Hillary also probably took every deduction possible. That's a lame excuse. And I'm going by what you said, which is that Hillary's returns were "satisfactory to viewers" but Trump's weren't. The only conservative to English translation of that is that Trump's returns are corrupt. And not necessarily outside of what the law permits; as you point out, there's evidence of illegal tax evasion.
As far as it making no sense for him to release what would ultimately be a hunting expedition for the left, I agree with that. The reason I feel he should release them is a) it's become common practice for presidential candidates to release them. Hiding them sets a new precedent for future corrupt politicians to hide theirs; and b) and more importantly,
because he said he would. He should be a man of his word. If he has something to hide, as even you admit he does, then he never should have said he would release them.
