Still mourning a Texas mass shooting, Democrat Beto O'Rourke gave his long-shot campaign a jolt by imploring a national audience that it was finally time for real action to curb the proliferation of high-powered guns in his home state and across America.
That was 2019, and the former congressman was running for president when he declared during a debate, “Hell yes, we’re gonna take your AR-15,” weeks after a gunman targeting Mexican immigrants killed 23 people at a Wal-Mart in O'Rourke's native El Paso.
