Whenever the Trump administration begins its "Deport 11 m illegals" attempt, go lay in some popcorn.
The DHS databases are never accurate or up to date, because they are a patchwork quilt, and people do stuff without telling the government.
Expect both legal residents and illegals to be deported, and expect a massive blowback as GOP representatives find themselves being hammered into the ground.
Save some special popcorn for the Florida Cubans. They think they are untouchable.
