Voters in three West Virginia counties won't get to use new touch-screen voting machines in the Nov. 4 general election, after the state Elections Commission decided not to certify the machines Monday.

Secretary of State Betty Ireland said the commission acted out of an "abundance of caution," after the machines' manufacturer, Election Systems and Software Inc., told the state that the new machines have different parts than the machines ordered by the state in advance of the 2006 elections.
