The Tories will have a harder time clawing back support than Labour because they’re still expected to deliver a Brexit deal, and they probably cannot accomplish that task. The business community is looking at a Conservative Party that can no longer represent them in a minimally acceptable way. The Tories will either crash out of the European Union with no deal (as the Brexit Party demands) or they’ll cede their position as a major party. The Labour Party can adjust to the surge for the Liberal Democrats by adopting a more coherent and consistent Remain position.
In America, the Republican Party has basically been taken over by a Brexit-type mentality, and the president’s decision to ramp up tariffs on Mexican goods is going to cause the same kind of economic chaos and hardship as a No-Deal Brexit will cause for the United Kingdom.
