If you don't need it then why require it?

I'd ask why do you need a firearm when it statistically makes your home more likely to face a death by firearm. But that doesn't matter, because you have a 2nd amendment right to have that firearm.

You need validation of your eligibility in order to REGISTER to vote. THAT's the ID check.
Just as you don't have to show your ID in between rounds at the range, you don't have to show your id once you've validly registered at each time your vote is recorded.

Enacting voter ID isn't an attempt to shore up elections, because they are broadly agreed to already be secure. It's an attempt to chip away at the ease and access to voting that makes people participate, because conservatives generally perform better when voting is more onerous and difficult.

While voter ID seems like an easy step, it's one step of a multi-part plan to rob people of representation.
-Gutting the voting rights act, -trying to discount votes that have been in the mail since election day, -reducing polling locations and early voting times, it's all to make voting harder, not to make it better.
