8/8 Our analysis points to politicians offering a partisan lense through which to look at policy-relevant events. Users who join the debate after politicians intervene are then induced to look at these events though the partisan polarized lenses offered by politicians.

7/8 Crucially, the effect is
- unique to politicians, who uniquely use partisan language
- stronger when politicians themselves supply partisan rhetoric in their own posts
- not about attracting more (or more politicized) or more posts
- coupled wirth more "tribal" language

2. We show that when politicians intervene, public debates become more partisan and polarized. More intervetnions? More polarization!

5/8 Our contributions is two-fold:

1. We describe when and how politicians intervene in public debates: they do not respond to timeline of event or debate, timing of posts by media, other influencers or politicians. This lends credence to a causal interpretation of our results.

4/8 We show that when politicians intervene in public debates surrounding policy relevant events (mass shootings), other users engage in more partisan (more politicians-like) and more polarised (more non-elite polarized-like) posts.

3/8 A growing literature has focused on “demand”-side stories: echo chambers, anonymity, etc.

But what about top-down polarization? What are politicians doing?

2/8 American public debate, like in this very platform, is increasingly partisan and polarised.

Every news event is soon viewed through partiasn polarised lenses.
