Harlow was one of many who shared their experiences of living without insurance during Saturday's rally. When she left a full-time job to start an education nonprofit, Harlow said, she didn't make enough to pay for insurance. Under Obamacare, she will qualify for Medicaid. But she said that is only because Maryland chose to expand Medicaid under reform. The law gives states the choice to opt out of Medicaid expansion, which many states chose to do. Because of this, many people will remain uninsured.
