Anyone hoping to do analysis leading up to or explaining the outcome of the 2020 presidential election would be well served to read Schultz and Jacob’s Presidential Swing States. Though dealing with more states than the first edition, this second edition does not overemphasize the earlier work's strict (and somewhat confusing) definitions. As such, it seems clearer and serves as a road map or, better yet, a travel guide to the states that may play a determining role in the outcome of the next election. Gone from this edition is any confusion about the number of states being discussed, but added is a separate chapter that explores a number of specific, key counties that may be even more determinative of the 2020 outcome in an especially close contest. . . this edition of Presidential Swing States will be of great value for the amateur political analyst as well as the seasoned professional.Summing Up: Recommended. Graduate students, faculty, and professionals.
