I’m a member of a political party (not in the US, thank the Gods) and was also in one in a different country I lived in and to me it looks a lot like the Democrat Party has started activelly campaigning, so party members are out and about in, amongst other places, social media, spreading the word about their tribe, maybe with some professional help.

This also explains the increase in articles posted in forums here like World and News consistently pushing a “vote Biden or get apocalypse” message, as well as the swarming nature of downvotes for even the most well thought comment that pick holes in that political propaganda strategy (such comments are swamped by downvotes, but the ones at the top or near of threads will over time slowly get more upvotes until they’re more than the downvotes).

It looks a lot like the kind of shit I saw in social media and newspaper forums in Britain during the Leave Referendum and that stuff later was discovered to have had massive manipulation from US-based interests via Cambridge Analytica and from Russia.
