a) Not enamoured of Sanders overmuch;
b) Really gets a kick out of kicking Clinton;
c) An outlet for the "Trendy Sorta Socialist" POV.
I mean, look at THIS article about Sanders--talk about "Damn him with faint praise!"

And this "reporting" on Clinton is so rife with errors that can be blown through with a simple Google--it isn't actual reporting, it's regurgitated pablum.

Their motto should be
"Jacobin--Everybody Sucks, And We're The Smartest People in the Room. Waaah. Waaah. Waaah!" Because that's frankly how their shit--and that's a fair term for it--reads. Insufferable hubris!
Their "ABOUT" page has a decidedly pale and mostly male perspective (none of the top-touted cheerleaders are POC):
Raison dêtre
Jacobin is a leading voice of the American left, offering socialist perspectives on politics, economics, and culture. The print magazine is released quarterly and reaches over 10,000 subscribers, in addition to a web audience of 600,000 a month.
Well-Deserved
The appearance of Jacobin magazine has been a bright light in dark times. Each issue brings penetrating, lively discussions and analyses of matters of real significance, from a thoughtful left perspective that is refreshing and all too rare. A really impressive contribution to sanity, and hope.
Noam Chomsky
Jacobin, whose ninth issue just landed, has certainly been an improbable hit, buoyed by the radical stirrings of the Occupy movement and a bitingly satirical but serious-minded style.
Jennifer Schuessler for the New York Times
I really like Jacobin its very explicitly on the radical left, and sort of hostile to liberal accommodationism. Theres a lot in there that I dont necessarily agree with, but its bracingly rigorous and polemical in a really thought-provoking way. Its a really well-done publication, almost preternaturally good.
Chris Hayes, host of All In w/ Chris Hayes
I love Jacobin, both the content and spirit. In a time of torpor bordering on despair, its great to see the youth embracing radical politics and serious thinking while also having some fun. And its a print magazine that looks great, too. Everyone should subscribe.

I don't blame you for not posting on that mess. Here's the guy who wrote it:

Looks like he writes the sort of college textbooks you try to buy used, because you don't want to spend a bundle and you know you won't get any money back on resale.
Here's another essay by that guy, written in 2008....you will notice some ....errrr...familiar themes:

Not saying he's a one-trick pony, but, well...
