Radley Balko uses the media positions on California’s Proposition 19 as a proxy to determine the actual bias:
For the last few months, my colleague Matt Welch has been tracking the positions of California’s newspapers on Proposition 19, the ballot measure that would legalize marijuana for recreational use. At last count, 26 of the state’s 30 largest dailies (plus USA Today) had run editorials on the issue, and all 26 (plus USA Today) were opposed. This puts the state’s papers at odds with nearly all of California’s left-leaning interest groups, including the Green Party, the American Civil Liberties Union, the Service Employees International Union, and the National Association for the Advancement of Colored People; progressive publications such The Nation, Salon, and The Huffington Post; and a host of prominent liberal bloggers. According to a CNN/Time poll released last week, it also pits the state’s newspapers against 76 percent of California voters who identify themselves as “liberal.”
On this issue, the state’s dailies are also to the right of conservative publications such as The Economist and National Review, prominent Republicans such as former New Mexico Gov. Gary Johnson, a growing portion of the Tea Party movement, and even Fox News personality Glenn Beck. (Beck has said he favors marijuana legalization, although he has been typically schizophrenic on Prop. 19.) So who are the newspapers’ allies? Nearly all of California’s major elected officials are against the measure, and the No on Prop. 19 campaign has been funded mainly by contributions from various law enforcement organizations, including the California Police Chiefs Association, the prison guard union, and the California Narcotics Officers Association.
It’s telling that the loudest voices opposing pot legalization are coming from the mainstream media, politicians, and law enforcement. The three have a lot in common. Indeed, the Prop. 19 split illustrates how conservative critics of the mainstream media have it all wrong. The media — or at least the editorial boards at the country’s major newspapers — don’t suffer from liberal bias; they suffer from statism. While conservatives emphasize order and property, liberals emphasize equality, and libertarians emphasize individual rights, newspaper editorial boards are biased toward power and authority, automatically turning to politicians for solutions to every perceived problem.
