Allegations of voter fraud -- someone sneaking into the polls to cast an illicit vote -- have been pushed in recent years by partisans seeking to justify proof-of-citizenship and other restrictive ID requirements as a condition of voting. Scare stories abound on the Internet and on editorial pages, and they quickly become accepted wisdom.
But the notion of widespread voter fraud, as these prosecutors found out, is itself a fraud. Firing a prosecutor for failing to find wide voter fraud is like firing a park ranger for failing to find Sasquatch. Where fraud exists, of course, it should be prosecuted and punished. (And politicians have been stuffing ballot boxes and buying votes since senators wore togas; Lyndon Johnson won a 1948 Senate race after his partisans famously "found" a box of votes well after the election.) Yet evidence of actual fraud by individual voters is painfully skimpy.
