Adopters must be at least 18 years of age and possess a valid photo ID.
But you don't need one to vote because that would be racist.
How is adopting a pet from a shelter like voting? Neither one is a right. There have always been restrictions on voting. There is no right to vote in the Constitution. Voting requirements can be defined by the state -- that was the Founders' intent and expectation.
Historically, much of the issue regarding voting rights arose because Democrats in southern states after Reconstruction did their best to suppress voting by black citizens. That was racist and needed to be addressed. The right of qualifying voters, though, still ought to reside within the jurisdiction of state government.
What is clearly wrong is to rob honest citizens of their votes by allowing fraud to be perpetrated. Photo identification makes fraud more difficult. It does not make voting more difficult, nor does it impose an undue hardship on poor people because these identification cards will be provided free of charge to voters when they register. You can get the picture taken and your laminated operator's license in your hand in a matter of minutes. It would be no different for a photo ID for voting.
Of course, 99% of potential voters already have a valid photo ID.
The only reason for politicians to oppose a photo ID is because they benefit from voter fraud.
