"Tens of millions" of people who can somehow get health care or fly or buy a firearm, yet you contend they can't vote. Sure, why not.

Ummm...there's lots of people who don't fly - about 10-15% of Americans have never ever flown. And who don't buy firearms - about 68% of Americans do not own a gun. And who are uninsured - although I'm not entirely sure why you think you need a photo id to get health insurance, about 10% of the population is currently uninsured. Do you genuinely not believe that such people exist?

Which is why I know this population of "Tens of millions" doesn't actually exist. Because if it did and the democrats actually cared like you claim, there would be a National Conversation about getting everyone free ID who is eligible for it

Are you not aware that there are numerous non-profit groups who work with the indigent, elderly and others to try to help them get documentation? One of the posters here used to talk about their time volunteering with such groups - I think it might have been David, but it's been a long time.

Are you also not aware that progressive Congressbeings do keep trying to get free ID cards for these populations from time to time, such as this effort from House progressives:

Today, U.S. Representatives Sean Casten (IL-06) and Cori Bush (MO-01) introduced the IDs for an Inclusive Democracy Act, legislation that would create a federal photo identification card that is free and optional for the American public.

“12% of Americans lack a drivers license and 11% Americans lack any form of government issued ID,” said Congressman Casten. “That’s 26 million people who cannot access the basic necessities to take care of themselves in our society, like getting a job, opening a bank account, or visiting urgent care. The IDs for an Inclusive Democracy Act creates no-cost federal photo IDs accessible to any American over the age of 14, and gives folks that important first step to provide for themselves.”

...but it doesn't pass by a mile in Congress, even though it's been introduced over and over again. Because even though progressives keep trying to get these ID's made available for folks who need them, these bills involve the federal government to spend money to help mostly poor, older, and often lower-education-level folks out. Which traditionally haven't been very popular among conservatives.

Did you really not know that progressives have been trying to have a National Conversation about this for many years, and it's just been shut down? If we're being cynical, I might intimate that it's because conservatives don't want especially care much about securing elections from fraudulent in-person voting (which is so unbelievably infrequent that no one's ever been able to provide proof of it happening often enough to matter), but that they actually want the impact of having a lot of people no longer being able to vote.
