We live in a country with a two-party system. We only get two real choices (usually) when it's time to pick a president. This means the people who decide each party's nominee play a hugely important role.
So who are these people?
For starters, it's a small group. Just 20 percent of American adults vote in presidential primaries. They tend to be older, whiter, and better-educated than your average general election voter.
Primary voters also tend to be highly partisan, which helps explain why ideas at the fringes of each party (free college for all, a giant wall along the Mexican-US border) gain traction during the primaries.
