Leftists are against ID laws because it lets them pander to low iq poor people and continue to say that Republicans don't want them to vote and want them dead. They want as many people voting for them as possible, no matter the legality.
Everybody has an ID, they're needed to drive, buy alcohol, buy cigarettes, and a ton of other things, but for some reason it's only bad to require an ID to vote.
Hmm, well, let me try to offer the non-strawman version of the lefty position on voter ID from what I've heard in discussions on the matter.
Poor people in urban settings are less likely to own a car than middle class people in suburban settings. Thus, the main reason to always have an ID is removed for some of these people.
Racial demographics show that anything that disproportionately affects poor people in urban settings automatically means it disproportionately affects non white people.
On top of that, you've got the difficulties involved in getting an id. For example, getting to the town hall in the town where you were born(trickier without a car), paying the small fee for the birth certificate, getting to the DMV, and paying for an ID.
Now of course, none of that is insurmountable, but it's not unreasonable to expect some people to say "fuck it" to jumping through those hoops. So, in the end, voter ID laws probably would lower non-white voter turnout, in a roundabout way. Those same laws would also lower poor white voter turnout.
How much difficulty is acceptable? I don't know, to me, voter ID isn't unreasonable, but then, it actually can be legitimately a pain in the ass to get an ID for some people...
The REAL question, if we're trying to weigh this logically, is this: Does the lowered turnout due to voter ID laws have as much a "disenfranchising" effect as having your vote's value lowered due to lack of voter ID laws allowing fraudulent voting?
What good does it do me to be able to vote without difficulty if 10 other people can fraudulently vote without difficulty? My vote doesn't matter anymore in that scenario.
