Rep. Jason Chaffetz has already drawn two challengers for 2018, Republican Damien Kidd and Democrat Kathryn Allen. But, according to history, the chances that they will be able to unseat him next year are remote at best.
An analysis by Smart Politics says Utah has a history of sending most U.S. Representatives back to Congress, especially when they win their party nomination. Chaffetz was the last person to defeat a sitting U.S. Representative for the party nomination when he beat Rep. Chris Cannon in 2008. It’s only happened two other times in Utah history. In 1914 freshman Congressman Jacob Johnson lost to Elmer Leatherwood and in 2000 when Derek Smith upset two-term Congressman Merrill Cook for the GOP nomination.
According to the breakdown, Nearly 87% of U.S. Representatives who won their party nomination won re-election that year, or 93 out of 107 tries.
Chaffetz also has been racking up big wins over Democratic challengers. In fact, Chaffetz owns four of the top-10 largest margins of victory for U.S. Congress in Utah history.
Smart Politics says only five times in Utah history has an incumbent won by double digits the previous election cycle and gone on to lose two years later, and none of those won by more than 25 points. Chaffetz won in 2016 by nearly 50 points.
