The recent addition of two more names to the list of Democratic primary candidates vying to face incumbent U.S. Senator John Cornyn again raises the immediate question of Cornyn’s prospects in 2020. We focus on University of Texas/Texas Tribune Polling data to look at Cornyn’s position among the Texas electorate to assess the position of the U.S. Senator that has held the office since 2002, a political eternity for a Texas Republican Party that took control of the state the same year. Cornyn was there at the beginning of the period of GOP dominance and has risen to one of the top positions in the Republican caucus in the U.S. Senate. Yet his standing in his home state, even through two successful reelection campaigns, has always suffered in comparison both to the political leaders that were his contemporaries and to the more recent generation of GOP elected officials who rose in his shallow wake.
