Nothing at all.Boris won?
What does that portend for the US of A?
I feel like 2020 here in the US will be more like Trudeau's victory in 2015 but on a smaller scale (Dems win back the White House, keep the House but either fail to win back the Senate or only win a slim majority).
Of course, Trump can win re-election but the UK's politics is different from the US's politics.
