Is the Uk election Johnson vs Corbyn result a prelude to Trump vs Sanders?

Don’t think so. One of those leaders will almost certainly be out of a job within a week, and their replacement will lead to a shift in the tenor of uk politics, and the Overton window moves.

By the time the DNC and RNC are held, the UK opposition will likely be led by an entirely different team, and the political environment will be in a different phase. Probably still arguing over Scotland and Brexit though.

If the Tories don't form a government, I could see Boris staying on as Leader of the Opposition, especially in an unstable hung parliament. He clearly boosted their support a lot and pretty much all the conceivable alternatives would have done worse. Then again, this is suspiciously similar to the logic for keeping Corbyn on as leader after the 2017 election.

I think people are underestimating their similarity. Insofar as there is a question of whether or not a hard left winger a la Sanders or Corbyn can both hold suburban/wealthy voters (the type who voted Dem in the 2018 midterns/against Brexit) or possess some sort of special strength with working class voters (Rust Belt WWC/Northern Red wall), it does seem likely to be a pretty good test, and I'm interested to see how it goes. Certainly, I think it's looking a lot thus far like they underperform with both your NJ-07/City-of-London-Westminister voter and with your average Monroe/Wrexham voter, which isn't a good omen for their chances.

In 2017, there were huge swings to the left in many of those suburban seats. Maybe not due to Corbyn, but he wasn't a big liability there. And I bet in most of these types of constituencies, the 2019 result will be better for Labour than the 2015 result before Corbyn was leader (even if there is a swing away from Labour compared to 2017, when Corbyn was also leader). So by this logic, Bernie will do better than Hillary Clinton in the suburbs, and it's just a question of the degree of the overperformance.
