The one he gave yesterday that has been eviscerated by the media as, armed with tweezers and a microscope, journalists set out to find anything and everything that is wrong with what he said.* Nonetheless, he laid out a strong case against Hillary Clinton, which isn't hard to do. The fact that you have Donald Trump, one of the most disastrously unelectable candidates in political history, barely outside the margin of error shows that you have serious problems if you're Clinton. Donald McClarey unpacks the speech and some good observations to go along with it.
*It's worth noting that the three articles on fact checking Trump were the top three results I got when I Google Searched "Fact Checking Hillary". Again, it's not like the media is biased or anything.
