Solution to Voter ID Legislation

The main argument against requiring voters to present a valid state id in order to vote is that it would create a type of tax on the poor that can't afford the id. The solution to this is simple: have the state or federal government subsidize ids for individuals that fall under a certain income level. As a conservative I am against governmental subsidies 99% of the time, but I feel after doing a cost/benefit analysis this would make sense. First, it would be cheap, since obtaining a state id card is very inexpensive. Second, it would take away liberals' only excuse to be against it, thus ensuring that left-winged groups like ACORN would have a harder time engaging in voter fraud, since every election they do.
