Maryland Gov. Robert L. Ehrlich Jr. (R) has embraced a legislative proposal to abandon the state's touch-screen voting machines for the coming election, in which he is a candidate, and to lease others that provide a paper record to verify results. Ehrlich's endorsement is the latest turn in the debate over Maryland's electronic voting machines that were used in nearly every polling place in the 2004 election. The state has committed $90 million to the system, which critics say is vulnerable to tampering. Last month, Ehrlich -- who championed the Diebold machines in 2003 -- express[ed] concern about reliability questions raised in California and Florida about those machines. A review of California's voting systems found more than a dozen vulnerabilities that security analysts said could be fixed. More than two dozen states now have some requirement for vote verification.
