Susan Collins: "It's difficult to envision" voting for Graham-Cassidy

Collins laid out a number of complaints about the bill that she doesn’t believe will be fixed.

“I’m concerned about the impact on the Medicaid program, which has been on the books for more than 50 years and provides healthcare to our most vulnerable citizens, including disabled children and low-income seniors,” she said.

“I’m concerned about the impact on costs and coverage. We already have a problem under the Affordable Care Act, with the cost of premiums and deductibles. And finally, I’m very concerned about the erosion of protections for people with pre-existing conditions, like asthma, arthritis, cancer, diabetes, and what it would mean to them.”
