Pennsylvania holds a special election for State House, 197th district, on March 21. This district is overwhelmingly Democratic and is in Philadelphia. On February 24, the Democratic nominee was removed from the ballot, after a state court determined he is not a resident of the district.

This is the same race in which Cheri Honkala, the Green Party nominee, was also removed from the ballot because one of her candidate forms was one day late. See this story. Pennsylvania does permit write-ins, so the fact that the Republican nominee is the only name on the ballot does not guarantee that the Republican will win.
