A runoff election occurs when no candidate in a race receives more than 50 percent of the vote. The top two vote-getters in each race advance to a runoff.

Harris County residents will see a runoff in the U.S. District 2 representative race.

In the race to replace outgoing Rep. Ted Poe, R-Humble, Todd Litton is the Democratic nominee, and Republicans Kevin Roberts and Dan Crenshaw will face off in a runoff May 22.

District 2 spans a wide swath of North Houston, including most of Spring and Klein. Out of nine candidates, Roberts received 33.03 percent of the vote, and Crenshaw received 27.42 percent.

If you did not vote in the March 6 primary elections, you can still vote in the May 22 primary runoff elections if you are registered. If you voted in the March 6 primary elections, you must vote with the same party in the May 22 runoff elections.

Early voting for the May 22 primary runoff election runs May 14-18. The last day to register to vote in that election is April 23.
