When is a valid ID required--and when is one NOT required?

Communists and their Democrat supporters bleat that "Makin' po' pipo hafta have an ID to vote beez voter suppression, comrades!  Dem awful Rethuglicans beez tryin' to end ouah precious democracy!"

Isn't it odd that no one wails and bleats and moans about having to show an ID for anything ELSE?  Just voting.  Hmmm....

Oh, and the above list left out "opening a bank account."  But the right side of the list omitted another huge and VERY popular "activity" under the harris regime that doesn't require an ID:  Entering the U.S. illegally.  

No ID of any sort needed!
