Needless to say, Cancun is a high-end tourist resort. There are people from all over the world flying in and out of there.
I think I heard that Oaxaca, another tourist resort, was also affected. And of course a lot of business people fly through Mexico City.
Napolitano has ensured that it will be all over the U.S. in any case. But I suspect that this Cancun connection may spread it widely in Europe and the Far East as well.
And yet our government doesn’t want to close the borders.
Well: It’s probably too late anyway.
