(There is only one team in US politics.)
Since the federal law requiring this was passed in 2005, it's another historically and unpopular president and fedgov.
(I am of course referring to Abraham Lincoln and the 1861 federal government)
The Federal government can't constructively require States to share the Real ID data with them, only ask politely, as that would go against existing Constitutional case law. Many States have declined to share Real ID data with the Federal government while still implementing Real ID. It is a bit surprising that California would agree to this.
From a state perspective, there’s a lot of benefit to exchanging this type of information across state lines through AAMVA. It reduces a lot of fraud, avoids a lot of insurance issues that cost the state taxpayers a lot of money. It has a lot of benefits to things like commercial motor carrier safety that have a direct benefit to the public.
For example, New York does direct entity to entity sharing of many driving records with Ontario and Quebec. The Canadians benefited because I don’t allow people with DWIs to enter Canada, New York benefited by keeping unsafe truckers off state highways, who were exploiting certain pools in Canadian regulations.
It’ll take a bit of time, But the long game here is that the United States will have a national ID system.
The big conflict is that states issue licenses (AB 60 in California, “green light” in other places) without regard to the ability to provide legal documentation of legal residency. Advocates fear that the sharing will be used by the hypervigilant immigration bureaucracy. States don’t enforce immigration law, but every resident of a state is at risk if people are driving around without insurance or without being subject to driving licensing laws. This also allows populations like the homeless to get IDs, But it’s being used as a punching bag by right wing commentators, rallying against illegal alien truckers and other nonsense.
The Supreme Court will do backflips to make the determination that they’re paid to make.
It's complicated within each party, but not overall. Idealogues prefer debating other idealogues because they use the same vocabularies and that preference is why they are always fighting, they like it. But the fat part of the curve in the middle is mostly made up of non idealogues who are quietly saying "can't you just shut up and compromise, let's be practical".
