What early method of nominating political candidates required people to hold meetings to discuss the positives and negatives of candidates?

The correct answer is Caucus. Political party caucuses was the dominant system for choosing candidates in the presidential nominating process. They are open to any registered voter in a party, although experts say the process is dominated by party activists. Caucuses are party meetings by district, or county, where party members gather to discuss the candidates and to select delegates to the next round of party conventions. Delegates selected at a caucus might go on to a county or state convention before attending the national convention in the summer. This process of gathering and talking distinguishes caucuses from primaries.
