While over 300 of the 435 House seats are considered safe for the incumbent party, there is a subset that is especially solid: those with no major party opposition. This year, 27 seats fall into that category, down from 42 in 2018. 19 seats have no Republican candidate on the ballot, while eight have no Democratic candidate.
The list falls into three groups, which are listed below. In the tables, one Margin of Victory column reflects the 2018 House election, with the other column being the margin between Donald Trump and Hillary Clinton in 2016. Asterisks in the House column mean the incumbent was unopposed in 2018.
Totally Unopposed: There are 11 incumbents that have the ballot all to themselves. Not on the list is GA-14, where the Democratic nominee has withdrawn, but remains on the ballot.
