You are just going off your imagination. There simply is little to zero proof that most Democratic voters are influenced politically by any non politician, talk show host, or political pundit. If any non politicians are politically influential why don't Democratic candidates seek any of their endorsements? Seriously, Biden sought the endorsement of Clyburn in South Carolina. He sought the endorsement of Democratic governors and senators, trade unions, etc. He didn't seek the endorsement of one non politician because their endorsements mean very little to most Democratic voters. In my memory the Democratic presidential candidates with the most celebrity endorsements during the democratic presidential primary were Bernie Sanders, Elizabeth Warren and Andrew Yang. They all lost to Biden who received very few celebrity endorsements during the Democratic primaries.
Republican candidates do frequently seek the endorsement of non politicians. They sought out trump's endorsement before he ran for potus. They used to seek out Limbaugh. They honored Brietbart. and Fox News because those voices hold a lot of sway with republican voters. Democratic candidates don't do that stuff with any news network or political commentator because none hold sway with the majority or a signifiant minority of democratic voters.
There just aren't any writers, or talk show hosts, or political pundits that Democratic candidates seek because none of those people hold sway with most Democratic voters political choices. I am open to any proof that I am wrong. Any.
