Twitter will run some political ads, just not from politicians. It seems well-intentioned, but might get messy.

Twitter announced details of its new policy banning political ads on Friday, saying that although politicians, political candidates and groups like SuperPACs will be banned from advertising on its platform, other groups and qualifying news organizations will be allowed to advertise on political issues. The policy, well-intentioned though it may be, will likely create confusion among campaigns and activist groups — and a headache for Twitter.
