538 polls-only gives Hillary a 99.6% chance of winning DC, but the projected margin is quite lackluster:
Clinton 67.6%
Trump 23.5%
Johnson 5.9%
For polls plus she has a 99.9% chance of winning, but the margin is still lackluster:
Clinton 71.2%
Trump 20.8%
Johnson 5.0%
For now cast she has a 99.0% chance. The margin looks like something out of Trump's dreams though:
Clinton 62.4%
Trump 27.9%
Johnson 6.7%
100% of the polls are from Google Consumer Surveys, though, with this one having the highest sample size at 73 LV. So who knows what's really going on there?
