So, 1.12 million registered voters out of an estimated 1.9 million population. http://worldpopulationreview.com/us-counties/fl/broward-county-population/

Lets do some subtraction from potential eligible voters:

1) Broward county public schools serve 271K students…the vast majority of which are too young to vote. https://www.browardschools.com/domain/13954

2) Population of younger than school aged children (I have no idea).

3) Illegal alien population estimated at 80K (but likely much higher) https://www.migrationpolicy.org/data/unauthorized-immigrant-population/county/12011

I dunno, that registered voter # seems kind of high to me…
