It was an innocent mistake that any politician could make, and having seen the video, I think Biden made a gracious recovery as best he could.
Only interesting thing about it is how demonized he would have been if he had been a republican doing the same thing.
I despise all of the rats, but I think that they are simply saying stupid things because they are off teleprompter and under stress. God knows I say some idiotic things in the course of a day, and I sure try to watch my words. It is not their words so much as they ideas that shock and offend me. Their ideas are so fiendish they are never articulated, lest their party whither away.
