Young people are also very tolerant and sometimes reluctant to confront those who hold different opinions.

Imani Cruz says she avoids political arguments with fellow students.

"They have a right to their opinion. I would not like anyone to put their opinion on me and I would not want to do that to somebody else," she said.

But many politically active young people do express their opinions, and hundreds took to the streets in Tampa this week to condemn Republican policies.

Most of the delegates inside the convention hall are mature adults, many having spent years working for their political party.

But every now and then you do see a young face.

One of the youngest delegates to the convention is 18-year-old Hamilton Zachariahs, who believes many people his age are disappointed by Obama.

"I think that young people will see that they are not getting the jobs they want out of college and what they were promised they did not get, and so I think a lot of young voters might see what Romney has to offer," he said.

Hamilton's father, Gary Zachariahs, an immigrant from India, thinks his son may run for office some day.

"The sky is the limit. This is America, of course!" he said.

And no doubt there will be other parents of other young political activists taking part next week in the Democratic convention, after these Republicans have gone home.
