Boris J and brexiteers operate exclusively at the superordinate level ("take back control", "big bad EU") while Jeremy C uses basic level instances ("workers' rights", support Arsenal, waterboarding ) in the main,
Lib Dems in between, with leanings to fantasy politics.
Just listen to BJ next time. In C++ he uses abstract base classes (i.e. no body) all the time.
