Conservatives believe that lefties don't want voter ID laws because lefties like to cheat; "vote early, vote often" isn't a saying that comes out of a conservative city. Church groups aren't as likely to help people violate election laws as labor unions are. Just sayin'.
But lefties often cry that there's never been any evidence of voter fraud; that's patently false, but even if it weren't, how would such evidence be gathered on a large scale? It would require ID in order to prove! It's like the millions of children who mysteriously disappeared on year when you had to start listing social security numbers of dependents on your federal income tax returns in order to claim a deduction for them...
So they won't allow us to gather the evidence of their wrongdoing, but sometimes it comes to us anyway:
But New York City’s watchdog Department of Investigations has just provided the latest evidence of how easy it is to commit voter fraud that is almost undetectable. DOI undercover agents showed up at 63 polling places last fall and pretended to be voters who should have been turned away by election officials; the agents assumed the names of individuals who had died or moved out of town, or who were sitting in jail. In 61 instances, or 97 percent of the time, the testers were allowed to vote. Those who did vote cast only a write-in vote for a “John Test” so as to not affect the outcome of any contest. DOI published its findings two weeks ago in a searing 70-page report accusing the city’s Board of Elections of incompetence, waste, nepotism, and lax procedures.When word of this got out, guess who and what "the establishment" complained about!
Go read the whole thing.
