Answer:
One reason why political candidates have to raise money is:
A. To pay for advertisements encouraging people to vote for them.
Step-by-step explanation:
It turns out that campaigning is quite an expensive endeavor. Buying TV time slots for advertisement, as well as producing those ads, costs a lot of money. Still, political candidates know how important it is to advertise properly. It is through those ads that they can reach out to people everywhere, present their ideas and proposals, appeal to obtain their votes, and even attack their opponents. However, candidates usually cannot afford it all by using their own money. They need to raise money, to receive donations, so that they can keep their campaign going.
