I think Trump will just run out the clock on this..say he’s considering releasing, still working on it, etc until it’s no longer an issue. In the general, you know Hillary won’t be pushing anyone to disclose anything.
The k1s and c filings are a problem for Trump until he knows he’s nominee. If he has the nomination he’s on a clear path to retirement. If he doesn’t he’s going back to business - but then all his competitors will know EVERYTHING. Trump always takes care of the downside as he should. Additionally, his returns will be used for OPPO research. He’s not going to give but one year and it will be late when he does. Or do the Gerald ford thing and release 10 years of summaries.
Then they an both make their ugly face and shout "Liar, Liar, Liar".
