Should voting be mandatory in the United States?

I run elections for a living at the county level, and here's the practical problem nobody mentions: elections are run by states, not Washington. There's no national voter roll, no national polling place system, no national anything. A federal mandatory voting law would mean Congress ordering 50 different election systems to track, fine, and excuse 230 million people with zero shared infrastructure. NCSL documents just how wildly election administration varies state to state. That's a logistical fantasy wearing a law costume.
