However, just one more notch in the "we need to demand IDs to vote" argument.
No, at best it means nothing. The question hasn't been "Is voter fraud possible?" It's been "Is voter fraud prominent enough that we need to enact new laws?" and "Is it prominent enough that it's worth disenfranchising actual voters?"
There hasn't been a good answer. The Republicans' last big stunt to try and prove its prominence turned out to be bullshit.
On a side note, it's always hilarious to see conservatives hate big government unless it hurts the poor, minorities, foreigners, or gay people.
