Democrat Barack Obama accused Republican presidential rival John McCain on Saturday of wanting to gamble with the retirement savings and health care of Americans by subjecting them to the uncertainty of open markets.
As the government prepared another costly bailout of the reeling US financial system, Obama said McCain's support for privatising Social Security and opening up the health care system to market forces would put Americans at financial risk.
He attacked McCain for supporting some privatisation of Social Security retirement funds, a proposal President George Bush made a centrepiece of his 2004 White House campaign but was unable to push through Congress.
"I know Senator McCain is talking about a 'casino culture' on Wall Street -- but the fact is, he's the one who wants to gamble with your life savings," Obama said at a rally in Daytona Beach in Florida, a state with a large population of seniors and retired workers.
"That is not going to happen when I'm president," the Illinois senator said, asking the crowd to imagine the fears of retirees who found their Social Security funds tied to the current market.
"We're not going to gamble with your ability to retire with dignity after a lifetime of hard work. We're going to strengthen and protect Social Security so it's a safety net our families can count on - today, tomorrow and always," he said.
