[2] Although the district appears rural, over 80% of its population lives in the heavily Democratic northern portion of Clark County.

The district has flipped between Democratic and Republican representation since it was created.

He was seated for the 113th U.S. Congress in 2013 as the district's first congressman, serving just one term before he was defeated by Republican Cresent Hardy in November 2014.

In turn, Hardy lost to Democrat Ruben Kihuen in 2016.

Kihuen did not run for reelection in 2018, and the seat was won by Horsford in a rematch against Hardy.
