I think it's interesting that you say Nunes, Jordan and King are not very visible, while AOC and Bernie are shoved down our throats.
I get 90% of my news from the newsfeed on my phone, which pulls stories from dozens of different sources. I think places like CNN have given Jordan, Nunes, King a lot of attention, at least as much as Bernie and AOC.
Where I see A LOT of attention on Bernie and AOC is FOX News and then to a MUCH greater extent than even FOX News is National Review, Breitbart, and the like. So for your perspective to be that AOC and Bernie are shoved down our throats it at least points me to an assumption as to where you get most of your information, which isn't necessarily directly from Breitbart, National Review, but just as likely from facebook posts, where those far right news outlets dominate.
