(CNN) Zika is here, in the USA. Fasten your seat belts because we're in for a bumpy ride. Local mosquitoes in the Miami area are carrying the Zika virus, and have infected at least four Floridians. In announcing this alarming news during a press conference Friday morning, Gov. Rick Scott, a Republican, added a sharp warning: "This is not just a Florida issue. It's a national issue -- we just happen to be at the forefront." Now all the falderal typical of American outbreaks will commence: Political posturing, hysteria versus naysaying, conspiracy theories, demands for safety and care and a daily mounting toll of identified cases. And this year the hoopla will unfold against the background of one of the ugliest, most deeply divided election years in modern history.Four individuals in Miami-Dade and Broward counties have been infected with the Zika virus by local mosquitoesLaurie Garrett: Yes, we all know Washington is dysfunctional these days, but this is about the nation's babies
