On Tuesday we learned that Mitt Romney cannot win a presidential election, even when he is Hillary Clinton. We also learned that Mitt Romney loses harder than Donald Trump, which is somewhat but not very interesting. Trump, after all, has strong support from the Fuck Everything Coalition, which hates Mitt Romney with passion and soul.
It is true that Trump also has strong support from certain Ists, but Ism cannot completely explain his rise. Ism, after all, is a weak force in politics due to the fact that its natural weakness is people bothering to actually oppose it (rather than anything particularly complicated), and the fact that Ism can only form a working political coalition by accident.
