Most believe "The Donald" has a Big Shtick, but Marco Rubio is not convinced. During a campaign appearance on 2/28/16, Rubio said,
"Trump is like 6'2'', which is why I don't understand why his hands are the size of someone who is 5'2. Have you seen his hands? You know what they say about men with small hands?"
What some people say is that small hands are a sign of a small shtick.
In the 1980's, Spy magazine called Donald Trump a "short-fingered vulgarian". Trump vehemently denied the blasphemous charge, saying "my fingers are long and beautiful, as, has been well-documented, are various other parts of my body.”
There is some science to suggest that what is important is not the size of the hands or the length of the fingers, but the length of the ring finger compared to the length of the index finger. If the ring finger (4th finger) is longer than the index finger (2nd finger, next to thumb) then the penis is more likely than not to be slightly longer than average. The ring finger and the index finger of Trump's left hand can be seen clearly in the second picture of the link below. Can your ring and index fingers hang with Trump's?
