If there’s one good thing to come out of the 2016 primary season, it’s this—disabled Americans are getting political and making politicians pay attention.

There are over 56 million Americans who identify as disabled, making them the largest minority group in the country. Add the tens of millions of caregivers and family members, and you’ve got a population large enough to sway any election. Yet despite this potential power, disability has rarely featured prominently in prime-time political speeches, especially not in ways that explicitly link the economic struggles of disabled Americans with those of other marginalized groups.

Clinton’s latest speech was not her first major engagement with disability issues, nor is she alone. Clinton released a plan to help people with autism earlier this year and started including disability rights in her stump speeches just before the New Hampshire primary. The Sanders campaign, likewise, has begun to talk about disability explicitly, linking it to their call for both health-care reform and jobs. After Sanders won in New Hampshire, he said, “We must pursue the fight for women’s rights, for gay rights, for disability rights.” Republicans have been quieter on disability, but both Jeb Bush and John Kasich have strong track records on relevant issues. Bush, of course, has left the race, and Kasich has not able to build on his second-place finish in New Hampshire.

Disabled Americans routinely struggle with economic, social, and cultural marginalization, a struggle often misunderstood as a factor of being disabled, rather than due to stigma. With marginalization comes silencing, passing, invisibility, and the fragmentation of the community. Disabled Americans have not consistently identified as a coherent interest group seeking to wield political power and forcing candidates to take notice. No wonder it’s been hard for people with disabilities to leverage their numbers into political power, and easy for politicians to overlook them.
