Question

most states use what to pick presidential nominees

Answer 1

Most states use a combination of primaries and caucuses to select delegates for presidential nominees. Primaries can be either closed (only registered party members can vote) or open (any registered voter can participate regardless of party affiliation). Caucuses, on the other hand, are local gatherings where party members discuss and vote for their preferred candidate. The delegates chosen through these processes then represent their states at the national party conventions, where the official presidential nominees are selected.
