The past couple days have been really active, posts-wise:

The Trump era has made Atlas much more active, but activity really spiked in December 2017 and hasn't let up since. This month will probably be another 53,000+ post/month.
More to your question - the past few days have been really active as well. Yesterday was just shy of 1,900 posts, which is a lot, and today might hit around 1,750 - 1,800.
It's pretty interesting to look at data like that, and how the amount of posts fluctuates. How come there's so many more predictions in 2004 and 2008 compared to more recent elections like 2016 and 2018?
