California lawmakers have rejected a measure that would have lowered the state's voting age. The proposed amendment to the state constitution would have allowed 17-year-olds who turn 18 by the general election to vote in primaries. Democratic Assemblyman Gene Mullin says the idea was to encourage voting among 18 to 24-year-olds. They have the lowest voter turnout of all age groups. Mullin says about 16 percent of the youngest eligible voters took part in the last election, a figure he calls a "disturbing and dangerous trend." Opponents worried that because the US Constitution sets the minimum voting age at 18, California election results could be questioned in a tight race.
