20 million people gained Medical Insurance under the ACA
Of those 20 million, over 7 million have since lost insurance (under Trump)
So prior to Obama, we had about 14.5% uninsured. It then dropped to 10.9%, but is now back to almost 14%. Aside from taking away the individual mandate, I really dont see what Trump did to make to the percentage higher.
The price on the exchanges were going up greatly prior to Trump coming into office, and perhaps people just could not afford it. Then when the mandate was taken away, the decided why not just drop it, especially since you can sign up even if your sick. So, I'll not have insurance and if anything happens, I'll just sign up then.
