In my recent post about the new PA voter ID law, I noted that a very, very significant number of registered voters – up to 18% of all registered voters in Philadelphia (home to half of the state’s African-American population) – may not currently possess an identification card that will allow them to vote in November. Supporters of these laws argue that requiring people to get an ID is a small price to pay in order to prevent voter fraud. It seems worth figuring out what the actual supplemental cost of voting is for those who currently lack required ID. I therefore present may totally back-of-the-envelope calculation of the poll-tax assessed by PA’s voter ID law. I use the working assumption that time is worth 7.25/hour. This is a fiction if the preparation time does not actually displace paid labor, but does allow us to monetize the cost of voting to be allocated to ID acquisition. I assume that photocopies cost .15 per page and that all mailings can be done for .45 first class postage. I also assume that this is all occuring in Philadelphia County, where there is public transportation to help you get to one of the five DMV locations in the county. In other counties, a person without a driver may have to spend even more to get cab service. Of course, some people will be able to get a ride – but given gas prices (and the cost of parking in cities), it seems unlikely that the effective cost of such travel will be less than the SEPTA public transit fare of $2 each way. More elaborate details on my calculations appear at the bottom of the post. And yes: I recognize that some people miss work, school or other activities in order to vote. I assume, however, that this cost is borne by all voters.
