If you pay $15K in federal income tax and then get $17K in federal returns, how much federal income tax have you paid? If you re-read what I posted before, I did NOT say that 50% people pay no taxes. In actuality, if you were to show how much of everything we buy is due to taxes, overhead due to regulatory compliance, administrative fees, etc, people would be stunned at how much we actually pay in total.
Nevertheless... because of the collective lack of attention spans/dissemenated information/whatever, the vast majority of us simply look at off-the-shelf sales tax and income tax to form our collective perspective of what we pay in taxes. Hence, my points on how this affects voting behavior.
And before GS pipes in with his usual thread derail attempts (at least any more than it is already), this DOES NOT EXCLUDE CORPORATE WELFARE with respect to what is paid in net taxes. Corporations are simply more aware of what they do and don't pay in order to put whatever resources on K street to make the system work in their favor. The rest of us peons don't have such luxuries for representation in DC. We end up paying the difference for those off-the-shelf goods to offset those costs.
So getting back to how this relates to the original OP, voter verification is at least a step in the right direction of addressing what is a bigger problem than people think. I would personally like it better if there were more consequences built in for ballot officials that commit such crimes, but this being the real world, I'm not holding my breath.
