2018 Pennsylvania's 18th congressional district special election
Pennsylvania's 18th congressional district
|Elections in Pennsylvania|
A special election for Pennsylvania's 18th congressional district was held on March 13, 2018, following the resignation of Republican Representative Tim Murphy. Murphy, who held the seat since January 3, 2003, declared his intent to resign on October 5, 2017, and vacated his seat on October 21 that year. Democrat Conor Lamb defeated Republican Rick Saccone 49.86% to 49.53%. Saccone conceded the race eight days after the election.
Eight-term incumbent Republican U.S. Representative Tim Murphy was involved in a sex scandal consisting of his allegedly having extramarital sexual relations with a woman and then asking her to have an abortion. This was particularly damaging because Murphy identifies as a pro-life politician. Murphy subsequently announced that he was resigning and that he would leave office on October 21.
Primary elections were not held in the race. Instead, nominees were chosen by each party. The Republican Party held a special convention on November 11, 2017, to choose a nominee through a conferee process involving 215 local Republican activists. The Democratic Party held their nominating convention on November 19, 2017. The Libertarian Party of Allegheny County and the Libertarian Party of Washington County nominated a candidate via party caucus.
Pennsylvania's 18th Congressional District is located in Western Pennsylvania and borders the state of West Virginia. It includes portions of Greene, Washington, Allegheny and Westmoreland counties. The district has a Cook PVI score of R+11. This was the last election for Pennsylvania's 18th congressional district held under its configuration made in 2011 by the Pennsylvania Legislature as new districts have been drawn in accordance with the ruling of the state supreme court in League of Women Voters v. Commonwealth of Pennsylvania and will be in effect for the main 2018 congressional elections in November. The bulk of the old 18th will become the 14th District.

The major party candidates were Republican Rick Saccone and Democrat Conor Lamb, in a district that Donald Trump carried by almost 20 points in the 2016 presidential election. The special election attracted national attention and was seen by many political analysts and commentators as a bellwether on the popularity of Donald Trump, Trump's tariffs on steel and aluminum imports, and the Republican Party. Saccone said the special election was a referendum on Trump's presidency and called himself "Trump before Trump was Trump". Prominent Republicans including Donald Trump (twice), Donald Trump Jr., Ivanka Trump, and Mike Pence came to the state to campaign for Saccone. The district was contested by a third-party candidate (Libertarian Drew Gray Miller) for the first time since 1996.
Republicans and aligned groups spent more than twice as much as Democrats and aligned groups on the special election. Although Lamb's campaign fund raised more than Saccone's campaign fund, Saccone benefited from far more spending by outside groups than Lamb.
The Republican Party and outside pro-Republican "independent expenditure" groups spent almost $10.7 million to support Saccone or oppose Lamb in the campaign, while $2.6 million in independent expenditures was spent in support of Lamb. Fourteen outside groups (seven Republican, seven Democrat) comprised over 95% of the spending. For the Republican side, the major groups spending money on Saccone's behalf were Paul Ryan's Congressional Leadership Fund, the National Republican Congressional Committee, the Republican National Committee, and the pro-Trump groups America First Action and 45Committee. For the Democratic side, the major groups spending money on Lamb's behalf were the Democratic Congressional Campaign Committee, Patriot Majority PAC, and the VoteVets.org Action Fund.
KDKA-TV hosted the first debate on February 19, 2018. WTAE-TV hosted the second and final debate on March 3, 2018, at 7 PM EST. The debate was hosted live by WTAE-TV along with the League of Women Voters of Greater Pittsburgh.

Lamb declared victory just after midnight on March 14. With all precincts reporting, Lamb led Saccone by 627 votes, a margin of 0.2 percent. NBC News declared Lamb the apparent winner early on the morning of March 14, based on the remaining absentee ballots from Washington County. The New York Times followed suit later that afternoon. A few other outlets declared Lamb the winner in what has been described as "a major upset", but others withheld judgment, citing the closeness of the race and the likelihood of a recount. Saccone conceded the race to Lamb on March 21, the day that the last votes were counted. Allegheny County certified its election results on April 2, making Conor Lamb's victory official.
Lamb's victory came primarily on the strength of winning the Allegheny County portion of the district by almost 15,400 votes. He lost the rest of the district by 14,700 votes.
