.@bcoyne: that'd be a clear 1st Amdt vio. What is it when #Twitter -which sells itself as a way for officials to reach voters- keeps some voters from doing that over ideology? Hasn't Twitter blurred the lines, made itself less a purely pvt co but one w/ features of a govt site?

.@bcoyne: "Twitter Government & Elections Handbook" hypes "politicians & government officials" using #Twitter "to connect w/ constituents". Let's say I sold chat s/w to govt sites & the s/w blocked some users based on ideology. Eg, Trump wouldn't see chat messages from liberals.
