Final answer:
The final blow to the health insurance movement was influenced by Republican opposition, the rise of conservative movements, and the cost issues associated with the Affordable Care Act.
Step-by-step explanation:
The final blow to the health insurance movement can be attributed to several factors:
- The Republicans' opposition to the Affordable Care Act, which led to calls for repeal and legal challenges from multiple states.
- The rise of conservative movements like the Tea Party, focused on limiting government spending and the size of the federal government.
- The increased cost of premium health insurance plans and political opposition to the ACA, including the Trump administration's vow to repeal it without announcing an alternative.
