Twitter's porous and subjective policies have enabled Trump to spread a steady stream of misinformation about the election to millions of Americans. Twitter only rarely applies fact-check labels to Trump's tweets containing false information about voting, and it's unclear how much labeling achieves. Just last week, Trump ran afoul of existing Twitter rules when he encouraged supporters to vote twice -- once by mail and again in-person, as a way of testing anti-fraud measures. Twitter hid the posts, while Facebook added a warning label, but neither noted that voting twice is illegal. Twitter says the new rules were needed to reflect "the changing circumstances of how people will vote in 2020."
