In the United States, getting an ID is expensive and time-consuming and is often inaccessible to many people, particularly those who don’t speak English, are poor, or work service jobs. These people are the same people who are historically marginalized and oppressed. This is why voter ID laws in the United States are fundamentally anti-democratic and disenfranchising.
If IDs were free and incredibly easy to get, I wouldn’t care about a voter ID law.
