I've been saying since 1988 (when I started voting) that it needs to be a requirement for candidates BEFORE THE FIRST PRIMARY/CAUCUS vote is cast:
a) present the last ten years of tax returns
b) all student records must be released
c) all military records must be released
d) all health records must be released.
Period.
You don't, you don't get on the ballot, and any write-in votes for you don't count. Period. No discussion, no debate. You have something to hide, you might be compromised and the pawn of a foreign government, so you can stop running right now.
The problem is getting this passed - because they all have something to hide. Yes, this is rumor, but one of the reasons it was suggested (and not just by talk radio or right-wingers) that Clinton would not release his health records (I don't believe he ever did) because he had had a cocaine habit in the 80s and had surgery to his nasal passages that he didn't want anyone to know about. (This of course was actually a MINOR type rumor when it came to the Clintons).
But Thomas Eagleton got disqualified for less psychosis than Donald Trump exhibited every damn day he was a candidate. No, Eagleton should not have been chosen - because a missileer or a SAC commander would have been thrown out of the military for his level of mental illness. But it's ludicrous to realize that the candidates themselves want their VP possibilities to submit to a rectal exam while they themselves hide all kinds of things.
