The U.S. has a tiny number of swing voters. Yet they wield outsized power. These are some of the most powerful voters in the world. If the polls are to be believed, and we’ll soon discover if they are, they are the types of people who would end Donald Trump’s presidency. Meet America’s shifting voters. They represent a small slice of the electorate yet wield a colossal influence, not only on the politics of their country but on the U.S. relationship with the world. They fall into several sub-categories — self-described independents, moderates and centrists; occasional voters; new voters; and third-party dabblers, and they tend to lack enthusiasm for either major party.
