I am assuming that Tom Aiken has applied his same rigorous standards to every male candidate that he has ever supported for president.  Allow me to quote his letter and adjust by using male pronouns instead of the female pronouns used in the letter.

"However, that (wo)man must be an honorable person whose honesty is beyond reproach. (S)he must be a person who wins (her)his nomination fair and square.( S)he must be a person everyone can respect regardless of party affiliation. The high honor of the position in history deserves no less.

When (s)he comes along, and not before,  I will proudly give (her) him my vote."

Wouldn't anything less than these requirements be a double standard?  

Hillary Clinton is, by far, the most honest and qualified candidate of 2016.  Do your research.  Also she is sane and competent.
