Now everyone--The Times and, sorry to say, MSNBC--is noting every missed syllable. The man has a stutter. I don't stutter but I am a mushmouth who speaks too fast and slurs words. I've had to overcome fear of public speaking. I have empathy for Biden. The press has empathy for no one (but Trump).
I'm a native speaker and I don't have a stutter and I misspeak ALL the time. I also only speak the one language so anyone that can speak more than one automatically gets more patience
