Paulette Hill spends up to 40 hours at a local barber shop a week registering people to vote and making phone calls to build support for Democratic presidential candidate Barack Obama.
"Every single vote counts," Hill said.
Meanwhile, Ann Christian has been doing a lot of the same work on behalf of Hillary Clinton, Obama's rival for the Democratic nomination.
"I will put signs up, and I will be down there cheering for Hillary and whatever I can do in the community," Christian said.
The jobs promise no money or fame, but both women said the payoff is trying to make the country a better place.
"This is serious business," Christian said.
Because North Carolina hasn't played a role in presidential politics in about 20 years, the work of local volunteers hasn't been important for a long time. Each sign Hill and Christian post and each voter they register could make the difference in the May 6 primary, they said.
"That is an exciting fact," Christian said.
