Maddow is a political hack who focuses on the implications of conspiracy theories. Her guests include John Brennan, Adam Schiff, James Comey, James Clapper etc. If you know who they are, that's all you need to know.
Maddow pushes an elitist world view that panders to the irrational fears of the fans. Sad that she gets to speak and spew her delusional rhetoric to such a large portion of the population.
With 1.8 million viewers in 2018, she hosts the 2nd most popular show on cable news. That is until the Mueller probe officially ended and within its release has proven President Trump to have not colluded with the Russians. Something Maddow has assured us has happened for years on end now.
