A little bit of googling explains everything:
Residents of Kentucky, Maine, Minnesota, Missouri, Montana, Pennsylvania, South Carolina or Washington, will no longer be valid to pass TSA-checkpoints with their state IDs. This means they'll have to bring a passport, military ID or permanent resident card next time they go to the airport, even if they're just traveling within the United States.
The new rule goes into effect January 22, 2018. This gives you plenty of time to finally renew that passport. The TSA has already begun putting up signage alerting travelers of the upcoming change in requirements.
So why are these states the only ones being affected? These states don't meet the federal government's minimum security standards, which requires verifying every ID applicant's identity, putting anti-counterfeit technology into the production of the card and conducting background checks on the people issuing the driver's licenses.
According to the TSA website, after January 22, 2018, you will still be able to use your state-issued driver's license to fly domestically as long as the state meets the Real ID requirements.

From about a month ago. Looks like the trump slump will hit the airline industry first.
"The site gathered flight-search data from 122 countries over the past five weeks, and found that weekly international U.S.-bound flight searches decreased 17% after the travel ban was announced. The number of flight searches dropped from 61.5 million per week during Obama's final days in office, down to 56 million during Trump's inauguration week, before falling to 50.9 million after the travel ban was ordered."
Bet you can still go and get yourself a high powered semi-auto gun with less ID in any of these states.

I expect your experience is too limited to form an valid opinion of de facto policy. Or even to know the written policy. But the internet is a good source for expanding one's knowledge.

Airline travel aside, schools in Windsor, Ontario, cancelled field trips to the U.S., across the river, for similar reasons about a month ago.
Stay calm, be brave....wait for the signs. Possibly precariously prevaricating.
