I don't see that the Dems have any cable news station that mirrors Fox. Take for instance Biden's progress on the bringing back the economy from the pandemic- new jobs, lower deficit, increased manufacturing, increased investment in rural america ....

If Trump were president, Fox would be all over his great triumph, ie only he could create such a miracle, along wtih a healthy dose of blame on Dems. Flip through the stations you mentioned- tepid support if any for the Democrats or their platform. Certainly no Biden worship the way you see on Fox for Trump. If anything- they are etiher on message with neo-liberal economics (conservative) , or critical of the Dems for not being progressive enough. Pretty much criticism from all sides.
