Well, that could explain that voter registration... sorta. IF this Roberta was also born in 1958, OK... And, yeah, the missing “a” on Robert could be explained as an error on the voter registration. But the Jr.? Hmmm.
My head hurts. Oy.
I wouldn’t worry too much about the voter registration indicating RDL is female. The simplest explanation is that is the result of a data entry error.
