You give talk radio far far too much credit. If they were as influential in presidential elections as some surmise then both McCain and Romney would have won.
I am not in lockstep with Trump he says things that are in line with what Bernie was for (trade tarrif wars, minimum wage) that if Hope all would be very critical of. So are we just supposed to shut our mouths and convince our ears that we heard something entirely different? Nope we aren’t liberals, we pull ours along but hold him to account.
Again I and many others are voting for the guy but that doesn’t mean we stop being critical
Not wise to alienate half (or more) of your listening audience. He can certainly make his views known without bashing Trump’s followers.
