For months and even years after George Bush beat John Kerry in 2004, Democrats, progressives and some voting-rights advocates raised questions about whether Ohio’s touch-screen voting  machines could be rigged.

Now it’s the GOP, proactively, raising questions about the machines. The Republican National Committee has sent a letter to Ohio Secretary of State Jon Husted citing unspecified complaints that some machines have recorded a vote for President Obama when the voter wanted to pick Mitt Romney.

It demanded that all touch-screen voting machines be recalibrated before Tuesday.

Brad Cromes is the deputy director of the Portage County Board of Elections. He says the county had only one issue with a voting machine this year, and it wasn’t a calibration problem. 

 “It’s not too dissimilar from using an ATM. If you have long finger nails or touch the ATM with multiple fingers, sometimes it won’t right away recognize what you’re doing. I think that’s a very similar thing to what you see happening on a voting machine.” 

Cromes says Portage County already plans to inspect all voting machines before they are sent to polling locations for Tuesday's election. That will include calibration testing.

A voter in Marion County claimed she had to try three times to get a machine to record her vote for Romney.
