Obama campaigned in Iowa on Saturday.
COUNCIL BLUFFS, Iowa (CNN) - Democratic presidential candidate Barack Obama said Saturday that his healthcare plan would bring costs down more than any of his opponents' plans would.
"Cost is the number one reason that 47 million Americans do not have health insurance," Obama said. "This is wrong, and it’s why my plan does more to cut the cost of health care than any other proposal in this race."
Obama said it would save the "typical family" $2,500 a year in healthcare premiums.
He added that the reason people don't have healthcare is because it's too expensive, not because they don't want it. He said that's why a mandated plan–what rivals Hillary Clinton and John Edwards are offering–won't necessarily solve the problem.
The Clinton campaign was quick to fire back.
"[Senator Obama] wrote a plan that leaves 15 million Americans without coverage," said Clinton spokesman Phil Singer in a statement. "That is unacceptable and Senator Obama should explain why he chose to leave so many people uninsured. When it comes to cutting costs, Senator Clinton's plan is just as aggressive, if not more so. The real difference is that her plan covers every American."
