A mandatory vote recount is underway here in Erie County and all across Pennsylvania.
When the counting is completed, the results should confirm the winner of the U.S. Senate race between republican Dave McCormick and incumbent democrat Bob Casey.
In the election office at the Erie County Courthouse, six ballot counting machines were humming all day Wednesday.
Four machines are recounting ballots cast in person at the polls. Two others are recounting mail ballots.
And as part of checks and balances the county swapped which machines are handling which ballots from how the counting was was done on election day.
Representatives for the republican and democratic parties and candidates are observing the process through the windows outside the election office.
