The Republican Party didn't hide the President of the United States from the public because he was no longer able to speak publicly.
Yes, they do hide Trump's health reports from the public - or rather he never releases any information like other presidents do. Hell, he GOT SHOT and never gave any details of what happened.
I agree that Democrats denying Biden's cognitive decline was a disaster.
The gibberish that routinely comes out of their candidate barely qualifies as speech.
The reality is, nobody who was wringing their hands about Biden's cognitive abilities, or his son's legal problems actually cared about either issue. If they did, they wouldn't have voted for an mentally declining criminal today.
