They are either completely or almost completely free to get in states already. The usual argument then swaps to how much of a pain in the ass it is to source ID documents and show up in person at the DMV or similar.
While this is from 2015, this does not appear to be true.
Those who do have a free ID, require a time consuming waiver process.
Free needs to mean free, "not fill out this stack of paperwork and we'll send it off to the state capitol and see if it'll get approved"
Means testing is expensive and time consuming.
Until the voter ID proposals address these issues, they aren't "securing our elections", they are putting arbitrary barriers in place of American's inalienable right to vote. Many of us will never support disenfranchising anyone.
