I'm a happy user of login.gov for various things (IRS, SSA, etc). But I was surprised that there's also id.me, which is used many places for the same thing, as if there's another login.gov. I'm still not sure why there is two.

Looks to be the USA equivalent to the GOV.UK One Login system which is also being pushed. Good to see goverments trying to working across departments to make things, eventually, easier https://www.sign-in.service.gov.uk/
Gov.uk can push a login system because it already has penetration across departments of the civil service.
It has that because of political will to implement it, combined with a coherent design language implemented as a set of well-thought-out components. It is a "pit of success" - departments get better quality for less expense, so they don't chafe about it being mandated.
I don't see the political will in America. The population hates anything that the other side touched. "The proud state of Mississippi was built on jQuery", etc.
