Not a real comment, unless questionably rhetorical questions count: why would Democrats be so concerned about having to prove their candidate’s eligibility in the way Gen. Dwight D. Eisenhower did if there weren’t fears on their side that what is coming from our side (and from Hilary’s, long ago) is true?
For the same reason they don't want their voters to have to prove themselves qualified or even if they are who they say they are. They are world class cheaters and frauds.
