Are these opinion makers/leaders not (highly) relevant politically? Some of them have a greater audience than many local politicians, whose sayings would undoubtedly be on-topic. And yes, these are political pronouncements. I'm not saying that what Beyonce says about hair style should on-topic (despite her large audience), but maybe if she says something about abortion and it gets discussed in the media, that could be political; or about the police.
But to keep this focused, the media personalities I'm talking about here, e.g. Limbaugh almost exclusively talk about politics. According to Wikipedia's bio of him:
Limbaugh has been one of the premiere voices of the conservative movement in the United States since the 1990s. He has been inducted into the National Radio Hall of Fame and the National Association of Broadcasters Hall of Fame.[4][5] During the 2020 State of the Union Address, President Donald Trump awarded him the Presidential Medal of Freedom.[6]
So why can't I ask here about what Limbaugh says about something political? (Similarly, I can ask the same question about Hannity etc.)
