I spend too much time listening to NPR. They regularly interview voters across the country, and both the men and women sound deeply ignorant of what goes on in this country, or their state, or probably their city, town, or village. They really don't appear to know what they're talking about, but they have what they think are sound opinions on politics. It started with television: people assumed what they saw on TV was true. These days, they assume if it's in print on the web, it's true. They are mistaken.
Furthermore, this TikTok script (?) is behind the times as to what a Vice President's duties are. It was Bill Clinton who gazed at his VP, Al Gore, and immediately assigned him various duties. Al Gore closed the field office of the Agriculture department that was located in downtown DC. And other duties. VP Harris has been all over the world, meeting foreign heads of state, has been to South and Central American countries, telling them not to come to the US, and doubtless performed other useful and skill-building activities. Joe Biden has used her talents, and expanded her experience, and he did that deliberately, hoping to pass the presidency on to her. He's passing it a little ahead of the schedule he would have preferred, but he seems to have done all he could to prepare her.
Well done, Joe, and Kamala!
