They meet stiff resistance because they're always done at election time and only selectively.

Voter ID laws are a non-starter because historically they've been used, along with literacy tests and civics tests, to disenfranchise people who can't get an ID. For example, in Idaho you must have "proof of your identity and age" like a birth certificate or citizenship certificate, plus proof of residency like a utility bill or rental agreement or employment record.

These things are easy for most people to provide, but people who are in unstable living situations may find these things impossible to provide. Requiring those people to provide ID at the polls would effectively disenfranchise them.
