The 2007 Allegheny County Executive election was held on November 6, 2007. Incumbent Democratic County Executive Dan Onorato ran for re-election to a second term. Despite speculation that Onorato would run for Governor in 2010 and not complete his term,[1] he faced only token opposition in the Democratic primary, and no other candidate filed to oppose him. Onorato won the Democratic primary in a landslide, and the Republican primary through write-in votes, enabling him to win his second term unopposed in the general election.
No candidates filed for the Republican nomination, though Republican County Councilman Matt Drozd launched an informal write-in campaign for his son, also named Matt.[5] At the same time, Onorato's campaign targeted likely Republican primary voters with a robocall the night before the election encouraging them to write in his name. Of the 3,431 write-in votes cast, Onorato received 1,844 of them, allowing him to win the Republican nomination, as well.[6]
