A measure that would make 21 the minimum age to serve in the Colorado legislature won the required two-thirds passage in the House on Friday.

"Young people from this demographic pay taxes, vote and serve in the military," said Rep. Michael Garcia, D-Aurora, sponsor of House Concurrent Resolution 1002. "This is clearly an issue of fairness."

Currently, the state constitution requires a person to be at least 25 to serve as a lawmaker in the Colorado General Assembly.

To change the constitution, Garcia's resolution next must earn two-thirds passage in the Senate and win final approval from voters as a ballot measure in the 2008 election.
