Here in State College PA, we're already having serious problems with the new touch screen machines at several precincts. A couple of polling places did not open at the regular 7:00 AM time. Lines are longer than usual in our little town, according to local radio, and some of that seems to have to do with voting machine problems and slow downs.
One day someone will have to explain how out of thousands of voting machines built and shipped, why only the ones in blue districts don't work correctly.
Another problem in small towns is the people working the polls are usually older and retired and really know nothing about computers. It's not a good combination.
