CARSON CITY, Nev. -- The Republican National Committee alleges voting machines in Nevada and five other states are flawed and improperly showing votes for President Obama instead of GOP nominee Mitt Romney.
In a letter sent Thursday to state election officials, the RNC's chief counsel says a "significant number" of cases have been reported of votes being placed for Obama when a voter cast a ballot for Republican presidential hopeful Mitt Romney.
Clark County Registrar of Voters Larry Lomax said his department has had about four complaints of the 400,000 ballots cast this election. In every instance, the issue was corrected before the voter cast his or her ballot, he said.
The RNC asks that machines be recalibrated and voters be reminded to double-check their choices before their votes are recorded.
Lomax said it is possible for the machines to fall out of sync, but the county recalibrates the voting machines at least once a day.
Similar claims were raised in the 2010 U.S. Senate race between Democrat Harry Reid and Republican Sharron Angle but were not substantiated.
