Final answer:
Primary elections are the most democratic method for choosing a candidate, while closed caucuses or small committees are the least democratic.
Step-by-step explanation:
In terms of democratic methods for choosing a candidate, primary elections are generally considered the most democratic. This is because primary elections allow party members to directly vote for their preferred candidate, providing a direct voice for party members in candidate selection.
On the other hand, the least democratic method for choosing a candidate would be through a closed caucus or a small committee of party elites. In closed caucuses or small committees, only a select group of individuals have a say in choosing the candidate, limiting the democratic participation of the broader population.
Overall, primary elections are more inclusive and allow for broader democratic participation compared to closed caucuses or committees.
