Romney's losing is the whole point. He lost and he still got more votes than Trump.
This is going to be a very unusual presidency for a lot of reasons. One of them is that it is effectively a "minority government," in the sense that Trump does not have a popular mandate. In some ways it is a government of one — Trump was elected as a Republican, sure, but he's not really one of them. He's got a lot of crazy ideas, like rebuilding the nation's infrastructure, that the GOP typically doesn't like. Big government stuff. And why wouldn't Trump like big government? He IS the government, after all, and he likes things big. He could end up clashing with his own party. He already is — which brings us back to Romney.
Curse Trump for making Mitt Romney relevant again.
