Near Total Absence on the National Media Would Suggest Maybe Not
One of the most important things a political party can do is to be visible, to make itself and its positions known to the American voter. Republicans and their media lapdog Fox News do a great job of this. Democrats don't even both to show up. It's not that so many people watch the shows, it that they get reported on Monday and get publicity for the people that speak.
On the Sunday morning news shows Republicans dominate. Is the problem that there are no leaders of Democrats to show up and defend their policies, or that there are just no policies to defend? Democrats are certainly invited but just fail to show up. If they lose in 2018 and 2020, they have only themselves to blame.
