As of early Wednesday morning, Mr. Lamb has declared victory over Mr. Saccone in the special congressional election in Pennsylvania, although his lead is about 500 votes with a few thousand absentee ballots still to be counted.

If the race is still too close to call after the absentee ballots are counted, voters or candidates could call for a recount or recanvass of votes, but the process is onerous. Voters have until officials are done with the computation of the votes on Friday to file a challenge with their county Board of Elections. The computation includes the counting of absentee ballots.

Omen for the fall election?
