Ireland decided this week to scrap their voting machines--like the ones here stored in Dublin. They're selling them for scrap metal, because they found they were too unreliable and too easy to hack. They'd only used them once, back in 2002, but that was enough. Unfortunately, America hasn't learned as quickly as the Irish.

They almost never deviated by more than a few tenths of a point from the actual electoral outcome, and when they did, it was a sure sign of fraud.
