Pennsylvania: Changes primary election process being considered | Meadville Tribune
In 1842, James Shellito of Sadsbury Township was upset with the procedure used by the Crawford County Democratic Party for choosing its nominees. He proposed a change that instead of a designated few choosing the party’s nominees for the general election in a behind-closed-doors session, all the registered Democrats should be allowed to choose the nominee. The matter was put to a vote and others agreed with Shellito. Thus, the “primary election” as it is known today was born. The primary election is defined as the election held by the two major political parties (Republican and Democrat) to choose their respective nominees for the fall election. Although states have primary elections, the types of primary elections differ from state to state.
