When no one laughed, Mansoor said, "I'll stop now," and began talking about his conservative platform.
"I'm running because I want to make a difference," he said. "There's too much overspending. There are many important issues to address: public safety, education and good quality of life."
Mansoor said his priorities would be to cut spending, cut taxes, help small businesses and bring jobs back to California.
Nguyen spoke "from the heart," said NAAP Treasurer Amira Mualla.
"I'm running to address the real-life challenges facing our state," Nguyen said. "That's the stark difference between me and my opponent. I'm not a politician. I never ran for office before. I'm not running to serve special interests. I'm running to serve the people of my district."
The event got even more serious when the candidates were asked what they would do for the Arab American community.
Mansoor, whose father emmigrated from Egypt, said he will represent a wide range of interests.
"I want to do the same thing for everyone," he said. "Most people want the same thing in their communities — they want a safe place to raise their families. I will have an open-door policy for everyone, regardless of who you are. I want to represent everyone."
When emotions are running high, and a group of people are getting attacked because of their religion or ethnicity, it's the perfect time for politicians to help foster understanding in their communities, Nguyen said.
Nguyen said as a Vietnamese America, he can relate to the anger and complaints he gets and hears about during holidays or religious observations.
Like Mansoor did earlier in the forum, Nguyen suffered a slip of the tongue in front of the crowd.
