The headlines about Donald Trump hitting new highs in national polls are tremendously deceptive, as they only measure his support among self-declared Republican primary voters, a small subset of the nation as a whole. For example, in [a] recent NBC/Wall Street Journal poll, Trump was the first choice of 27 percent of the Republican voters who responded. Given the weighted samples in this poll (38 percent identify as Republican or leaning Republican) this translates into Trump capturing the support of about 11 percent of American voters in total. In the same poll, 37 percent of Democratic voters supported Democratic contender Bernie Sanders. Given the weighted samples (43 percent identify as Democrat or leaning Democrat) that translates into roughly 16 percent of all American voters. Additionally, in a recent Quinnipiac poll, Sanders beat Trump in a head-to-head matchup - by an even larger margin than Hillary Clinton did. But in terms of coverage by the mainstream media, Trump is besting Sanders 23 to 1, by some estimates. Some of this can be explained by the fact that Trump is the GOP frontrunner, and Sanders has consistently run second to Clinton. But it's also partly because of what a spectacle Trump has made of himself - and because the media has consistently treated Sanders as a marginal candidate. Media executives view Trump's outrageous antics as good for their bottom line. "Go Donald! Keep getting out there!" Les Moonves, the chief executive of CBS, [recently] cheered.
