I suppose that you were hoping me to claim that proof is needed, then pop back that no proof exists that "widespread" voter fraud exists. Obama did not need proof that mass shootings were "widespread" to call for gun restrictions, in fact, they average 2 per year. One can certainly say, and proove, that voter fraud is more frequent than mass shootings. Asking to see the same valid, state issued, photo ID that is required to cash a check, board an aircraft or to legally buy a gun, ammo, alcohol or tobacco is not an unreasonable restriction to cast a vote. If the presentation of an ID is unreasonable "discrimination" to exercise the right to vote then it is also unreasonable "discrimiantion" to keep/carry a gun.
