There's nothing really surprising here; right wing talk radio (and Fox news) flourished when conservatives were in dissent, in resistance. Now its the Dems who seethe righteous anger, and tune in with baited breath as each termite gets a chomp in on Trump.
Compounding the matter, as posts in this thread suggest, a lot of conservatives are just contrarians that got to bitch to survive. Trump won, the GOP held Congress, and conservatives are still pissy. And declaring, with the piety of a reformed drunk, they'll not watch Fox news again.
It's rather pathetic how conservatives are throwing it all away.
