From what we've heard in the news, you'd think that only Hillary Clinton and Barack Obama are trading jabs over health insurance plans, but apparently, this isn't the case.

While her husband is no longer running for president, Elizabeth Edwards hasn't shied away from criticizing John McCain's health plan.

According to ABC News, Edwards has criticized McCain for not offering a universal health care plan, or at least one that would make it illegal to reject consumers based on a pre-existing condition. Currently, anyone diagnosed with a major illness will either pay more money for health insurance, or be denied coverage altogether.

She has also criticized him for enjoying the coverage of a federal health insurance plan for the majority of his life, a plan that McCain does not endorse opening up to the public.

Edwards has been recently diagnosed with incurable breast cancer. And, since McCain was diagnosed with skin cancer in 2000, according to Edwards, neither she nor McCain could get coverage under the health insurance plan McCain proposes to endorse.
