Maddow and Chris Hayes are the two tv journalists I trust pretty implicitly - because both are authors and bomb-throwers outside of their cable lives.
Jesse Berney on Twitter and in Rolling Stone. I also admire the analysis of the Keeping it 1600 crew. I like both their writing and the Keeping It 1600 podcasts.
David Farentholt, obviously.
In these times, Anne Helen Peterson on Buzzfeed is writing a lot of really good stuff about celebrity media as a tool of normalization.
The Slate Political Gabfest has been a staple of my diet for close to a decade now, and I don't see quitting on it anytime soon. Dickerson might be trying to keep everyone calm, but I think he's balanced out by the other two raising genuine concerns.
If you want to truly get your blood up, go track down Chris Hedges at TruthDig. Both he and Matt Tabbi are very much in the "death to neoliberal capitalist structures of power," which I can find kind of difficult but necessary.
I also recommend the Pantsuit Politics podcast - two women, one on the left and one on the right, discussing contemporary issues. Both provide nuance and a sense of calm even though "this is not fine."
I am woefully bereft of good podcasts/regular columnists of color (aside from Ta-Nehisi Coates, who I will read anything by).
