To cast a primary election ballot in New Mexico, voters must declare a political party. But that could change if lawmakers pass Senate Bill 16 this month to adopt open primaries.

Supporters say New Mexico's electorate has changed, with 40 percent of those between the ages of 18 and 24 choosing not to affiliate with a party.

The state does allow same-day registration, but Sila Avcil - the executive director of the group New Mexico Open Elections - said that still means more paperwork and time is needed to vote in a primary for those who choose not to register with a political party.

"Under this bill," said Avcil, "what would happen is - if I'm a registered independent - I would just show up and say, 'I'm an Independent, here's verifying my registration, and today I would like to vote as a Democrat or a Republican or a Libertarian.'"

She said the bill would prohibit voters from participating in more than one party primary.

Critics of open primaries worry voters could affiliate with one party over another to influence that party's nomination, by choosing a candidate they feel would be easier to defeat in a general election.

Research shows the percentage of independent voters in New Mexico is growing.

From 2000 to 2022, Democratic registration declined from 52 percent of the electorate to 44 percent. At the same time, the state's Republican registration declined from 33-percent to 31-percent.

Avcil said the trend suggests a change would be helpful.

"I think this is the right time,," said Avcil, "because we constantly are seeing every year an increase in independent registration - particularly by young people. They're registering more and more as independent."

New Mexico is one of just 10 states with closed primaries. Avcil noted that this is the 10th year the bill has been introduced in the Legislature, but she said she believes there is more support this time around.
