Probably the majority of US citizens do not want a federal ID card. A number of states refuse to comply with the RealID requirements on their drivers licenses and others are dragging their feet. As a result the drivers licenses of some states won't be suitable for federal identification soon.

At one level it's a bit silly as many have passports and drivers licenses are (almost) a form of universal ID. On the other hand, I sympathize with the push against mandatory federal ID.
