It exists in some areas. Its the Democrats in some states that mess it up! The easier it is to vote, the more it benefits the Dems.
In VA, at least in my county, they requrie a photo ID, compare you to the roster of people registered to vote at that precinct, and literally ask you what your address is when they are in posession of your ID (99% of the time it's a drivers license). No games... Old lady doesn't think you should be there, they really get serious with the questioning. Misbehave, you get escorted out...
