If creationism becomes the biggest issue, then it is unfortunate. There are far more bigger and more important issues out there to act upon.
IMO people don't really care that much about evolution/creationism in schools -- it's more of a flashpoint, a reaction against the atheist liberal indoctrination that is rampant in many public school systems, from sex ed classes to no prayer in school to no Christmas celebration to skewed teaching of history and polisci.
The sad state of public school education is indeed an important issue; this is just a convenient though perhaps ill-chosen vehicle for objection.
