Just to clarify the analogy for this Californian, which of those island nations shares a 2,000 mile land border with the United States?

Were you aware that most of our borders are on the ocean? Have you ever heard of a thing called a "boat"? Have you ever heard that Cubans and Haitians come to FL in rafts, boats, or anything else that might float for even a short time?
Nah, I didn't think so.

How many Cubans and Haitians "hit the beach" on the Florida coastline in a given 24-hour period?

Cochise County, Arizona (with only 80 miles of border) has an estimated 2,500 or so mixed nationalities climbing the fence every night. The Border Patrol manages to catch an average of about 480 per night.
