According to U.S. Census Bureau, there are more than 56 million people with disabilities in America.

Despite their numbers, people with disabilities are not as politically well-organized or well-funded as other interest groups, such as gun enthusiasts or abortion rights advocates. This explains why disability issues don’t get much attention on the campaign trail. Only Hillary Clinton, Bernie Sanders and Jeb Bush have specific sections on their campaign websites devoted to disability rights. These candidates mainly focus on their records supporting the Americans with Disabilities Act and similar laws. Rick Santorum folds his authorship of The Combatting Autism Act into a section called “Valuing the dignity of every human life.”
