Beto O'Rourke took the national stage by storm in 2018, when he ran against Republican Ted Cruz in a race for the US Senate. O'Rourke only narrowly lost to Senator Cruz, in what should have been a walk in the park for the Republican in the safe red state of Texas. Now people can't stop talking about the young, three-term congressman from El Paso, and despite that Senate loss, speculation that he could challenge Trump for the presidency in 2020 has reached a fever pitch.
