Although I haven't been reading it as much since the election - maybe the editors are pushing the anti-Trump angle hard like NYTimes has been shamelessly doing recently. It's writers are very 'internationalist' and focused on geopolitical diplomacy so a lot of them are falling under the 'I'm appalled at Trump and must bring it up at every moment to show that America is still okay'.
It's tough being a news junkie and not being a typical foaming at the mouth US mainstream liberal these days (which to the surprise of many in that category does not make one a right wing Trump supporter, nor American for that matter).
