Daily Kos users are f**king insufferable, yes. I used to read Daily Kos Elections pretty regularly until Dave Nir started his "Anyone who criticizes Hillary Clinton gets banned" policy, and pretty much purged the site of anyone not mentally stuck in 2005. Kos himself is also a massive idiot.
The last time I checked in the comments section was calling Jeremy Corbyn too radical for the UK and agonizing over him not resigning.
To be fair, DKE is slowly turning towards being impressed with Corbyn, and making fun of how weak May is.
And primary talk overall is banned, and always has been.
