But McCain's voter fraud worries – about Acorn or anyone else – are unsupported by the facts, said experts on election fraud, who recall similar concerns being raised in several previous elections, despite a near-total absence of cases.
"There's no evidence that any of these invalid registrations lead to any invalid votes," said David Becker, project director of the "Make Voting Work" initiative for the Pew Charitable Trusts.
Becker should know: he was a lawyer for the Bush administration until 2005, in the Justice Department's voting rights section, which was part of the administration's aggressive anti-vote-fraud effort.
"The Justice Department really made prosecution of voter fraud of this sort a big priority in the first half of this decade, and they really didn't come up with anything," he said.
"ACORN is stealing the election" is not a serious argument. It is the last rationalization of a campaign that is going to lose, casting about wildly for some way to excuse their terrible, terrible performance in this campaign. It's pathetic.
