With the stroke of a pen, New Mexico Governor Michelle Lujan Grisham enfranchised almost 350,000 independent voters recently by signing a bill for open primaries. Just a few years ago, bills to open the primaries were languishing in the state legislature, as they have historically across the country. But as more and more voters leave both parties and declare their independence, the political system is buckling. And as independents begin to organize and speak out, it’s going to continue to buckle in their direction.

In 2004, there were 120,000 independent voters in New Mexico. A little over 10 years later, when the first open primary bill was introduced, that number had more than doubled. That bill never even got a hearing. But today the number of independents in New Mexico and across the country is too big to ignore. Independents are the largest group of voters in ten states and the second-largest in most others. That’s putting tremendous pressure on a system that wasn’t designed with them in mind.
