There is a thriving cottage industry these days of books debating the stupidity of Americans: whether the assertion is true, if so what causes it, what the ramifications are, and what, if anything, can or should be done.
This is also a hot topic, increasingly, in the popular press. The lead story in the July/August 2008 _Atlantic_ asks "Is Google Making Us Stoopid?" and the answer argued with supporting evidence is, in brief, yes, while on the same newsstand (for those who actually still browse bookstores and newstands) the July _Esquire_ makes a glib attempt at the opposing view in A. J. Jacobs' "You (We) Are Not Stupid."
For a magesterial overview of how we got to the current situation, see Susan Jacoby's _The Age of American Unreason_. For a reflective consideration of the impact of the Internet from a cautionary side, see Lee Siegel's _Against the Machine: Being Human in the Age of the Electronic Mob_. For the more comforting counterargument that pop culture and video games are making us smarter and better prepared for the future, check out Steven Johnson's _Everything Bad Is Good for You_.
How does Shenkman's book fit into this subgenre? Well, the subtitle is "Facing the Truth about the American Voter." It argues voters vote irrationally, based on cultural myths and effective advertising or TV spin, rather than thoughtful consideration of political platforms, actual current events, or their own best interest. It is written in a breezy, light style, so it is a quick read, and seems to be targeting the audience it describes as stupid--the ones responding to the polls in overwhelming numbers demonstrating ignorance of basic geography, civics, history, etc. Why would those already not in agreement with his argument read this book? Well, the author is a professor with a track record of successfully marketed breezy books on the impact of myth in American politics and history, and I suspect he would like to see this book assigned in college classrooms.
It doesn't tell me anything I didn't already know or suspect, but it does effectively use anecdotal evidence and documented data to establish for a general audience that there is a serious problem here, and that instead of blaming the media or opposition political parties, maybe we should stop romanticizing the driving purpose of "the American People" and hold ourselves, collectively, more responsible for challenging the way we allow the media (in particular television), the consumer culture, and political campaigns marketed like new cola drinks to manipulate us so easily. Perhaps we get what we deserve, but to the detriment of the entire planet.....
His advice? We need to demand debates about important issues, turn off ALL the spin machines, and evaluate ideas. We need to admit how stupid we are, and that more advanced degrees aren't needed, but some heavy emphasis on basic civics classes (and lots of remedial review!) The power of polls should be curtailed, and all polling should require those polled to demonstrate their knowledge of a subject before they offer an opinion on it.
Although there are no footnotes (which scare "the American People" he describes away from books, anyway), a brief bibliographic essay at the back could provide those motivated to probe deeper into some of the specific topic areas he raises. Although I doubt a majority of Americans will jump on this bandwagon, I think any extended conversations about our need for more civic awareness, striving a little bit harder for what Jefferson envisioned as an informed and critically thinking electorate, would be good for America.
