For your average Dim voter, a criminal history is a resume enhancer. Dims are immoral by nature, so the have no trouble supporting their fellow travelers.
If you have a jebbush v Hitlery race, Hitlery will win. jebbush will get rinos but very few real conservatives. Hitlery will still get most of the Dims; she will get a few less blacks than zero of course, but that’s the limit of erosion she’ll have to worry about. The funny thing is, the black voters won’t stay home because of some e-mail scandal, they’ll stay home because Hitlery ain’t black.
What difference does it make? Any Republican candidate would be too polite to introduce any negative information about Hillary into the campaign.
