Answer:
A) Primary
Step-by-step explanation:
At the beginning of the primary process, many politicians express their interest in participating in the electoral course. However, as the question explains, many of them cannot raise enough funds or find sufficient support to take part in the first primaries: the Iowa Caucus and the New Hampshire primary.
Others, do participate in the first primaries, but get poor electoral results, and consequently drop out of the race. After the first two primaries, only three of four candidates on average continue participating in the primary process.
