Four ways the US government shutdown could end

The US government has entered a shutdown after the Senate failed to pass a funding bill, marking the first federal closure in nearly seven years. Senate Democrats blocked a Republican spending bill that would have kept the government operating until November, though three Democrat-aligned senators broke ranks to support it. As the shutdown continues, political pressure will mount on both parties, with Democrats potentially facing increasing strain as government employees and the general public begin to feel the effects of curtailed services.
