There’s an untold story from the 2016 election that should encourage Democrats and worry Republicans. It happened in Houston, the nation’s fourth largest city in population and the hometown of former President George H. W. Bush. To be precise it’s Harris County, Texas—which consists mostly of Houston—that we’re talking about.

On November 8, Hillary Clinton lost Texas to Donald Trump by 9 percentage points. But she won Harris County by an astonishing 13 percentage points. And that’s not all. Republicans lost every county-wide race (including incumbents) and 24 of 24 judgeships. The son of Lt. Governor Dan Patrick was among Republican judges who were ousted.
