Logic and reason tell us that anyone who can't vote because they just can't manage to do the paperwork to get a photo ID likewise can't do other actions that require a photo ID, such as buying alcohol, buying tobacco products, flying on an airplane, buying a Costco membership, opening a cell phone account with a major carrier (and making account changes at the store after that), picking up a prescription, etc., etc.
Let's be honest: Liberals want to make it as easy as possible for the least educated, least successful, least competent among us to vote because they know that most of those people will vote Democratic. After all, in 2012, 2/3 of high school dropouts voted for Obama, and they accounted for 3% of all voters, which was most of Obama's margin of victory (3.9%).
