for the same reason..they’re mostly all hiding stuff... and they know they can do it... after Obama’s successful two elections hiding even his basic identity, true name, real birth certificate, citizenships, immigration papers, social security (other than a stolen account), college transcripts and finance files, and (if any) selective service registration .... etc.
point being, nowadays no candidate is gonna tell the American public anything they don’t want to... since... the electorate doesn’t require it anymore to elect them.
And yes, I figure Mr. Trump may have a lot to hide, if only because of the mess our tax code is in and how complex his financial affairs must be.... So I think we may agree on that.
Hopefully Trump used every loophole afforded to him in the tax code to lay as little tax as possible. I hope Cruz and the rest of them did the same and you did the same. This is how decent people think. This approach will fail like all the others did.
