Super PACs affiliated with school choice groups — the Illinois Network of Charter Schools and the Urban Center — have helped blow the election caps off of most of the school board races in Chicago. Super PACs can raise and spend unlimited sums but cannot coordinate directly with candidates or donate to them. So far, these two groups have mostly spent their money on mailers, text messages, and ads in support of candidates (in some cases, in opposition). The groups have spent a combined $1.34 million since September.
