The correct answer is:
A) Unqualified candidates can be elected to local office simply because they are the same party as a popular presidential candidate.
Explanation:
Local elections are held separately from national elections to avoid people voting for a candidate only because they belong to the political party of their presidential candidate or because they want to punish a political party. Separate local elections also avoid competing for attention at the same time, campaign messages are more likely to be heard when people are not distracted with the national elections and people can focus on local candidates proposals.
