This video from Media Matters shows not only that the "widespread voter fraud" doesn't exist, the myth is primarily believed by Republicans, who learned of it at the feet of Fox News.
That’s thanks in part to conservative media’s near-constant, baseless fear mongering about voter fraud over the past few election cycles. Right-wing outlets, and especially Fox News, have bombarded audiences with exaggerated or misleading claims of voter fraud to create the impression that Democratic victories at the ballot box are largely the result of illegal election rigging. Stories about dead or non-eligible or non-existent voters appearing on voter rolls are regularly touted as proof of nefarious activity, even though those voter registrations never actually translate into votes.
The most memorable example of this kind of fear mongering came during the 2008 controversy surrounding the non-profit group ACORN. A number of ACORN voter registration employees had been discovered submitting false or duplicate voter registration forms (the laws in many states require third parties who register voters to submit all forms they receive). Fox News devoted countless segments to the story in order to hype hysteria about widespread voter fraud, despite the fact that those forms never produced an actual fraudulent vote. ACORN was eventually cleared of charges of orchestrating voter fraud, but half of all Republican voters still believed ACORN helped steal the election for President Obama in 2012 -- two years after ACORN had closed down.
Misinformation about voter fraud isn’t only the fault of conservative media. As GOP statehouses across the country have pushed for restrictive voter ID laws -- laws aimed at disenfranchising typically Democratic voters -- local news outlets have repeated Republican talking points about the threat of voter fraud without fact-checking them.
Democracy is failing because the media isn't doing its job.
