Senility

 Since we are going to be hearing about Joe Biden's age until Election Day, I think at some point journalists need to examine the obvious mental and cognitive decline that Donald Trump is demonstrating. The example given above is only one. He confused the leaders of Turkey and Hungary; he thought Hungary shared a border with Russia. 

Part of the issue is the media's inevitable desire to tell the same story over and over again (Butter emails!) and endeavor to give a false sense of balance by playing up the foibles of one candidate to balance the manifest batshit insanity of the other. 

The other is the fact that while both Trump and Biden are showing their age in certain ways, Trump is - and always has been - a fucking idiot. Not just "stupid" but arrogantly uncurious about the world. Biden was never the Smartest Guy In The Room, but he has spent his life working in politics and public policy. That's how his brain is wired. Age has also made his stutter worse, which means he's not great at the forward facing parts of the presidency. Meanwhile, Trump never understood shit about government or governance, never wanted to learn and now appears to be in such emotional turmoil over his various legal troubles that he's decompressing before our eyes.

Even if Trump is in jail by this summer, there's a decent chance he's still the GOP nominee. It's time to start looking at his obvious aging problems just as rigorously as the media is looking at Biden's.
