Voter registration has increased nearly 7 percent since New Mexico's last primary election, but a growing share of the electorate can't cast ballots in primary contests.
Independents — those unaffiliated with a political party — are the fastest-growing part of the electorate.
According to the secretary of state's office, nearly 1.3 million are registered to vote — an increase of 6.6 percent since the 2012 primary election.
There are nearly 997,000 Democratic and Republican voters, an increase of 4 percent. Only Democrats and Republicans can vote in their primary contests.
There was a 16 percent increase in independent and minor party voters. They account for 22 percent of registered voters, up from 20 percent in 2012.
About 47 percent of voters are registered Democrats, and 31 percent are Republican.
