Turn on MSNBC or NPR or CNN.
They're all left wingers and Democrats swallow their swill without question. Your suggestion that Democrats don't listen to pundits is nonsense and illogical.
I didn't say Democrats don't listen to political pundits. The category political pundit is a huge category and includes a ton of people. So yes Democratic voters and elected Democrats do listen to certain political pundits, historians, economists, social scientists, etc. So yes if you add up every media company or every political talking head, you can say of course these people collectively have influence with Democratic voters, but that doesnt add up to there being one political pundit, historian, economist, or social scientist I can name that has political influence over the majority of Democratic voters or the Democratic party. Some individual Democrats may like Jake Tapper, Cornel West, Kimberlé Crenshaw, George Stephanopoulos, Lester Holt, Ta Nehisi Coates, R. Maddow, Corey Robin, Ezra Klien, Noam Chomsky, Paul Krugman, David Shor, Raj Chetty, Thomas Piketty, Nikole Hannah-Jones, and many many many more but also a lot of Democratic voters have never heard of these people, or dislike those people or don't agree with them or don't even see them as Democrats, etc.
So that is the question I answered which was which non politician has political influence on most democratic voters or the democratic party. I can't think of any.
You just took huge media companies and said turn them on, they are all leftwingers and that democrats swallow their swill without question, but of course the vast majority of Democratic voters don't watch MSNBC, or CNN and NPR hosts are like non descript and not even famous. That's why you can't name a single person and show ok here is this person's actual influence with the majority of Democratic voters or elected Democrats. You have to pretend to know its true.
