truth and you do it in an entertaining way that you will win way more fans than the media has made enemies for you. and i am proof of that. donald trump is proof of that. there are plenty of other people in this new populist that approve of that. with the exception of the president, i'm obviously the biggest personality in that ecosystem. but there's lots of us. there are things that even in publications will bracingly and that's not okay. >> after words airs on book tv every saturday at 10:00 p.m. and sunday at 9:00 p.m. eastern. you can watch all previous after words programs on our website, booktv.org. >> so what can we learn when we look at the searches? so if you remember in the 2008 presidential election, all the way back then, barack obama was elected president, he defeated

john mccain and there was a big question after this election did race matter in the voting, did people care that obama was black when deciding whether to vote for him and this kind of a classic question that could be complicated by social desirability bias, if you ask americans, 98 or 99% say they don't care, they didn't care that obama cus black in the -- was black and a lot of people assumed that there wasn't a post racial society back in the day and the idea that voters voted for obama and they said that they didn't care that obama was black. so could you use google searches to potentially because people are so honest because people tell google things that they might not tell things socially unacceptable, could you use google searches to get the real answer to the fact that it

played a decision in people's voting decision. what i did i made a map of racist search volume on google and this is the percent of google searches that include very, very charged racist word, i won't say that it out allowed but you can guess what it is and the first thing that struck me about this data, first was how common the search was and in the time period i was using people are making these searches, either racist searches in the frequency as they were searching lakers, migraine and daily show and economists, so it wasn't by any structure of the imagination strange search. these are mostly for joke mocking african americans, the theme of the searches, the other thick that struck me about this map is it looked very different from the map i would have expected of racism. so if you had asked me where racism was highest against african americans in the united states i would have guessed that racism is predominantly concentrated in the south, if

you think of the country's history, civil war slavery, we think of racism as having north and south divide and definitely racism is highest -- some of the places it is highest are in the deep south, southern mississippi and southern louisiana, but you can also see in the map with darker red meaning a higher frequency of the searches that it's also higher in many places in the north in western pennsylvania, in eastern ohio and industrial michigan, up state new york, rural illinois, i think the real divide this search data resales is not north versus south, it's east versus west. you see it's much, much higher east of the mississippi river and then kind of drops pretty substantially west of the mississippi river. so once i had this map, i wanted to see -- because people are so honest here, could you use this data to measure how much obama really lost in the 2008 election

and, of course, you can't just compare racist searches to votes for obama because it might be that places that have high racist searches would oppose any democratic candidate and that wouldn't be a fair comparison. so what i did was i compared obama's vote total to previous democratic candidates such as john kerry in the previous election who was a white candidate and ranked similarly liberal and what you see when you do that and you can read the paper, read it in the book, it's a very strong significant relationship that places highest racist search volumes, these places in appalachia or industrial michigan support obama much less than previous democratic candidates. and you can start controlling for anything you like, you start controlling for education or demographics or political views or cultural views and nothing changes the relationship that that was a big factor and

overall i conclude that obama lost 4 percentage points from racism which is much higher than you get from any other measure and he got about 1 to 2 percentage points from increased african-american turnout. so this tapered language in the academic world for a little bit and recently when the trump phenomena was starting that trump was saying a lot of racially charged, racially charged comments and people were questioning how is he doing so well even though he's saying these things that you're not supposed to say and was racism driving some of his support and nate for "the new york times" asked me for data, he had data on support for trump in the republican primary, of all the variables whether age or education or economics or trade exposure the single highest

correlation he could find was the racist search volume for trump. this, of course, does not mean that everybody who supports trump is racist but it does mean that -- that some of his supporters were and it did drive some of the progress in the -- in the primary. >> and you're watching book tv on c-span2. we are in las vegas. that's the freedom fest convention, gathering of libertarians and one of them is dinesh dsouza, exposing the lie of the left. you could easily be forgiven for thinking you're given the 2016 platform of the democratic party. >> the nazis issued on official platform, it had, i believe, 25
