This is not unreasonable nor disrespectful, considering that one of the requirements to be President is that one be a natural-born citizen.
The contrast is interesting- Bush just had to provide those dental billing records to prove he showed up on base on some day or other, but Obama gets, so far, a pass from the strident voices of MSM.
And Clinton got away with never revealing health records, though a White House physician got canned for refusing to give “allergy injections” from an unmarked vial (if I remember this correctly, it was way back in the copresidency)
