Ask most Democrats, and they’ll tell you the big problem with Fox News is that it spreads disinformation, enabling Republicans to manipulate gullible voters into voting against their own economic interests.

After Tuesday’s crushing defeats in Virginia and Pennsylvania, longtime Democratic strategist Ruy Teixeira said the real danger posed to Democrats by Fox News is a little different. According to Teixeira, Democrats have become so dismissive of Fox News that they automatically dismiss any inconvenient issue the network covers, even ones that turn out to actually matter to real voters.
