10 percent of Cuyahoga County's Voting Machines Fail Pre-election Tests

CLEVELAND, Ohio -- About 10 percent of Cuyahoga County's voting machines checked so far have failed a pre-election test, once again challenging public confidence in the election system.
With just weeks until the May 4 primary election, the system's manufacturer, Election Systems & Software Inc., has been unable to find what is causing the machines to arbitrarily power down and lock up during a test.
The problem showed up about 10 days ago when the Cuyahoga County Board of Elections began a series of routine tests on the voting machines. The machines froze during a specific test done to ensure the optical scanners were reading paper ballots correctly. At different points in that test, the machines simply started powering down, then freezing.

But it is hard to tell how pervasive the problem is. Board members were told at their meeting Tuesday that some machines that first passed the test, later failed when the procedure was repeated.
Employees stopped the test after 19 of the 279 machines had problems. Those 19 were put aside, and the staff started the tests on the others all over again.
By the time they had retested 200 machines, nine of those that initially passed had failed the second time around. snip
