We know that the hard-left right now, they're angry.
As major news outlets began calling the race for Cruz around 10:30 p.m., the incumbent senator was leading in the low single digits - a much closer margin than most polls had shown in recent months. "They're filled with rage and hatred for the president". It was seen as not only a referendum on the Trump presidency, but also issues of gender, race, and violence.
Cruz was backed by his 2016 presidential opponent President Donald Trump and other prominent Republicans.
As Cruz has embraced the White House, O'Rourke concentrated on mobilizing young voters, Texans living along the U.S. -Mexico border and people who moved to the state from elsewhere. He set fundraising records and made Cruz work for the victory, but Cruz ultimately pulled out a three-point victory.
Cruz, who was first elected to the U.S. Senate in 2012, has been a prominent, if not contentious, figure in the Republican Party. And though he was tested by O'Rourke, avoiding what would have been a monumental upset means that remains a possibility.
"My confidence is in the people of Texas", O'Rourke told reporters on Monday night, moments before staging a raucous rally with Mariachi band at the University of Texas at El Paso, mere blocks from his home.
MSNBC apologized for airing the expletive via local Austin, Texas channel KXAN soon after. O'Rourke argued that would help a Democrat win statewide. Republicans have held every statewide office in Texas since 1994, reports Refinery29.
