I&#x27;m skeptical that&#x27;s a significant factor, because right-populists seem to be gaining even in countries, like Denmark and the USA, which have a large portion of mainstream media and politicians hostile to mass immigration. In that case, immigration opponents can&#x27;t claim that nobody takes their concerns seriously, or that you&#x27;re not allowed to criticize mass immigration, because many mainstream outlets and figures are doing so. But the media support seems to if anything just help their cause: years of Fox News harshly criticizing illegal immigration from Mexico feeds well into Trump&#x27;s strategy of doing the same thing, but with the rhetoric amped up a few notches.
