Twitter puts an end to political advertising

SAN FRANCISCO, California - Twitter announced an end on Wednesday to political campaign and issue advertisements on its service, calling it an important step in reducing the flow of election-related misinformation.

But some of its users might face an unintended consequence or two.

Among those potentially affected could be public-interest nonprofits eager to reach an audience larger than their official followers, challengers to incumbent officeholders, and - obviously - political consultants who make a living placing ad buys for their candidates.
