“They choose not to have any ability to check citizenship”
Blame HAVA/FEC/EAC. In response to the Hanging Chad of 2020 FOD Friends of Dodd wrote the HAVA Help America Vote Act. HAVA gives state and local election officials FREE MONEY to create new, computerized voter registration and vote casting and counting systems. HAVA/FEC/EAC FREE MONEY is sought by state and local officials who do not want to beg the state legislature for money.
It is Federal money that pays for MOTOR VOTER that registers people to vote when they apply for a drivers license or state ID. That software is written such that both the state worker and applicant have to go out of their way to find and check the box that they are not citizens... or they are felons or others not qualified to vote in that state.
Age is asked and known. But teens 16-17 are registered thanks to the design of the software.
In general, government software, both federal, state and local is of much less quality than that of Fortune 100 companies.
Both MAGA and non-MAGA repeatedly ignore why we have the mess that we have. In 2013 GA Secretary of State Kemp did not want to beg the legislature for money as he would then owe those legislators an IOU to be collected later and impact his ambitions to be governor. So KEMP took FREE MONEY from HAVA... from FOD Friends of CT Sen Chris Dodd. What could go wrong with FREE MONEY? The CT FOD wanted to make money. They had high expenses due to all the campaign contributions they were required to make. So CT FOD Friends of Dodd outsourced the development of Voter software to India with just 2 H1b types to shuttle back and forth between India, CT and GA.
Recently Trump dismissed the board at the head of HAVA/EAC. But last I checked the staff still implements their own enlightened view of what should be done.
In California, there is no way to avoid registering to vote, legal citizen or not, with their DMV in house computer when one does any type of drivers license transaction.
