why are the democrats shutting down the government

The Democrats are seen as shutting down the government because they are refusing to support Republican short-term funding bills that do not include extensions of certain health care provisions. Specifically, Democrats are insisting on keeping enhanced tax credits under the Affordable Care Act and reversing Medicaid cuts that were implemented earlier. They argue these are essential to help millions of Americans access affordable health insurance. This disagreement over health care funding has led to an impasse with Republicans, who control both chambers of Congress but cannot overcome the Democrats' filibuster in the Senate without their votes. As a result, when the Senate failed to pass either the Republican or Democratic funding proposals on the deadline, the government was forced to shut down. Both parties blame each other for the shutdown, but the core issue is the Democrats' demand that any funding bill must address health care subsidies and Medicaid funding, which Republicans and President Trump have rejected.
