I've been pretty miffed about why Trump's failure to disclose his taxes has not been made a Big Deal.
Trump has not failed to disclose his taxes. He has not disclosed them, but that is not therefore a failure. If he had (oh say) a legal obligation to do so then did not do so, then not doing so would be a failure to do so.
Anyway, there has been (or at least so I thought) a lot of pressure put on him to appease those that would apply such pressure--under the guise of a call for transparency, which has been made into a big deal. Didn't he in fact disclose a partial summary or some such a couple months back?
At this point, I can't imagine him releasing his tax returns in full disclosure fashion.
