Voter ID laws not as bad as Democrats claim
Most of the arguments against the laws are circular claims that there is a lack of evidence of fraud. Of course fraud is hard to detect without the ID requirement. As for not changing the results of an election, it is hard to quantify the deterrent effect of people not committing voter fraud because they are afraid they will get caught of they have to produce an ID. I suspect people are more likely to cheat if they think they will not get caught.
The Brennan Center for Justice points to large numbers of voters who can be disenfranchised, but that doesn’t mean many election results will change.
