"Sen. Obama's plan is not universal," Edwards told reporters Thursday in Des Moines. "It does not require that everyone be covered, and as many as 15 million Americans would be without coverage. And I've seen an estimate that up to 90,000 Iowans would be left without coverage."
Obama spokesman Tommy Vietor took issue with Edwards' comments.
"Sen. Obama's plan is universal, but the difference between his plan and Sen. Edwards' is that he doesn't believe the government should force people to buy health insurance they can't afford, which is why his plan does more to cut costs than any other," Vietor said.
Hillary Clinton has similar criticisms of Obama's plan, and highlighted them in a campaign appearance in Iowa this week. Both Clinton and Edwards require Americans obtain health insurance, but differ on how they would reach that goal.
"There are very substantive policy differences between us on this issue," Edwards said. "I just want to make sure caucus-goers are aware of that."
