The Democrats would like for people to believe they were not cheering the Republicans' failure to pass ACA repeal and replace legislation, but they were cheering. To them it's a political victory despite the financial pain and suffering imposed on the American people.
Political victory at all costs is the history of congressional Democrats in recent times, and it starts with their way or no way, or we're going to be called obstructionists. They call it compromise. Start with trying to fix the ACA, as an example, and then they will negotiate a few crumbs to the Republicans.
