Dessert mogul Ben Cohen takes on e-voting

Ben Cohen, co-founder of Ben & Jerry Ice Cream, is launching a grass-roots campaign to require paper receipts for all electronic voting machines.

The campaign, run by Cohen’s Web-based group TrueMajority, kicks off Tuesday in Washington. About 400,000 people have already joined the group, though.

Cohen and computer security expert Dan Wallach hope to convince legislators to require a paper trail before the fall election. So far, only California has ordered vendors, including Green-based Diebold Inc., to print ballots for every voter.
