Dang, Eagle, you are correct that trump did take a test and he did get 30 out of 30.. Of course you got the name of it wrong.. but what the heck... so did I when did a 30 sec search.. no bad..

But is this test all that makes a person cognitive enough to run the country?

Lets remember that the test trump took was only a test for early mental deterioration.. not if he had the smarts of A gnat..
and as for Joe being a stone.. no way.. only the wishful desire of the trump cult makes that comment as a replacement for anything real to criticize..

So, be sure to read the end ...

If you look at the test, it’s pretty hard to see how you could not score a 30. You see a picture of a lion and have to identify it as a lion? That old joke about how the elderly and toddlers are subject to the same indignities seems pertinent here: Is this really the bar that needs to be met to demonstrate full mental capabilities?

Well, according to those who study dementia and other mental deterioration, yes.

Update: This was all well and good until Trump himself made reference to his MoCA score in an interview with Reuters.

“[Trump] blamed his three immediate predecessors, Bill Clinton, George W. Bush and Barack Obama, for failing to resolve the [North Korea] crisis and, a day after his doctor gave him a perfect score on a cognitive test, suggested he had the mental acuity to solve it.”
“‘I guess they all realized they were going to have to leave it to a president that scored the highest on tests,’ he said.”
The original post above was meant to explain to readers why the seemingly easy nature of the test was not a reason that Trump’s passing it should be pooh-poohed. After all, the lingering question was one of Trump’s cognitive abilities and whether or not he was affected by the early stages of mental decline, perhaps in the form of dementia. Mocking as easy a test meant to detect that particular thing is as dumb as mocking someone for passing a blood test.

But the flip side of this is that this is not a test you should brag about — any more than you should brag about passing a blood test. Not only did Clinton, Bush and Obama have no idea how Trump would perform on such a test, but neither they nor anyone else should see Trump’s perfect score on the test as indicating anything other than “this person’s brain is not showing obvious signs of deterioration.”

Democrats Want Biden to Relinquish Sole Authority for Nuclear Launches
Now, lawmakers of the current president’s own party are asking President Joe Biden to surrender that unilateral power.

Giving one person such authority “entails real risks,” according to a letter endorsed by 31 Democratic members of the House. “Past presidents have threatened to attack other countries with nuclear weapons or exhibited behavior that causes other officials to express concerns about the president's judgment.”
