The Democrats are asking for the following:

• Extension & expansion of health-care subsidies under the Affordable Care Act (ACA). This was set to expire at the end of 2025, and would drive up insurance costs for millions of low-income and middle class families if not subsidized.
• Reversal or protection against Republican-led cuts in Medicaid / other health programs. The BBB removed a lot of people from Medicade coverage, they want to prevent it from getting worse and guarantee protection for US citizens.
• A meaningful say in any continuing resolution (CR) or stop-gap that reopens the government.

Essentially, Republicans are trying to ram through legislation that fuck over a lot of people. Democrats are trying to prevent a lot of people from being fucked over, and have essentially told Republicans that you need to work with us on these things....like, you know, a functional government is supposed to do.
