 The president also sharply criticized former President Trump. And overall, this was a very solid stump speech. But it was also done with a teleprompter and comes amid more reports that raise questions about the president's stamina and behavior in various meetings over the past few months and year. He's reportedly had an increase in the number of times he's lost his train of thought or trails off, while at other times he's very engaged. And while this was a very well-received speech in Wisconsin, I don't think it erases any of those doubts.
