Look, it's not complicated. The idea that voter ID is preventing any significant number of fraudulent votes is based on nothing more than nonsense memes found on right wing websites. Actual voter fraud almost never happens in large enough numbers to affect even local elections, let alone state or federal ones. Add in the fact that elections are largely staffed by volunteers and managed in hundreds of local precincts that vary in how they manage/store ballots, if the GOP was actually worried about the validity of the vote, they would fund more modern equipment, paid poll workers, and standardized voting equipment/procedures.
I did my PhD dissertation on voting laws. Voter ID is entirely, 100% about making it harder for reliable Dem voters from voting. Any suggestion otherwise is partisan nonsense.
