MIAMI - Republican John McCain’s “Straight Talk Express” bus took a little detour today, depositing McCain at a Cuban-American restaurant in Little Havana.

McCain, who likes to keep a cup of coffee at his side most of the time, decided to sample the espresso served up at Cafe Versailles, ordering a cup at a window for ordering items to go.

Taking a sip from the small ceramic cup, he must have found it a pretty strong brew. He pumped his fist as he tasted the coffee.

“Do I have any enamel on my teeth?” he asked. “Delicious!”

This was after McCain stopped at La Casa del Preso, a memorial to deceased and current political prisoners in Cuba. After a tour inside, he spoke to a group of Cuban-Americans gathered outside.

“Buenas tardes,” he told them, then admitted that was pretty much the extent of his knowledge of the Spanish language.

In English, he proceeded to criticize Cuba’s communist government and vowed that sooner or later the Cuban people would be free.

Somebody in the crowd thought McCain should pick a vanquished Republican adversary, former Massachusetts Gov. Mitt Romney, as his vice presidential running mate.

“Romney for vice,” was one sign held up by people in the crowd.
