(CNN)Nicolette Carrion did a little dance when she cast her first ballot ever in last year's election.
"Now that I'm 18, I'm able to invest in my future in being able to vote, in a way I wasn't able to before," she said.
Carrion's right to vote at age 18 comes because of the 26th amendment, which marks its 50th anniversary on Thursday.
"The 26th amendment is part of our country's journey to expand and actually make our democracy more inclusive," said Mike Burns, national director of the Campus Vote Project, an organization that works to remove barriers for students and provide information needed to vote.
