Listen up, filthy humans, The Pale Orc is speaking. Why would you not show an ID to vote?
That seems reasonable enough.
The problem is, monkeying with the voting rules has become an entirely political game. Both parties' concerns about the "sanctity of the vote" are disingenuous. All either side cares about is tweaking the rules so that their supporters are more likely to vote, and the oppositions' voters are less likely to vote. Republicans currently presume that poor, disaffected people will be more likely to vote Democrat, so they want rules that will scare these people away from the polls. Democrats want to pave their way and make it as easy as possible.
Republicans pretend they are worried about fraud, and Democrats pretend it's all about the "will of the people". They're both lying. They just want power.
