With Japan in a desperate struggle to keep a series of nuclear reactors from total meltdown, the words "nuclear safety" have been on everyone's lips.

But it wasn't always this way: During the 2008 presidential campaigns, Sen. John McCain (R-AZ) took to mocking then-Senator Barack Obama (D-IL) for saying he would "consider" offshore drilling and that nuclear energy would need to be safe.

"Bla, bla, bla," he said, eliciting cheers from a crowd gathered in Cedar Falls, IA.

Some 70 percent of Americans said they were worried about the safety of nuclear energy, according to a recent poll. That figure was up from just 57 percent a week before the Japanese quake, tsunami and nuclear crisis.
