John Kerry Criticizes Mitt Romney's 'Positions On Healthcare'

Senator John Kerry (D-Mass.) criticized Republican presidential candidate Mitt Romney on Tuesday, saying the former Massachusetts governor "is going to have more positions on health care than he has voters."

"Mitt is sort of running against Mitt right now," Kerry told "FOX Business Network."

Kerry has voiced his opinion on Romney several times in recent days, previously saying the Republican presidential hopeful had flip-flopped on "every major touchstone of American politics" during an appearance on "Meet the Press."

"There are few people I've met in public life who have changed on as many issues as he has," Kerry said.

In the past, Romney has had hurled similar criticisms at Kerry. A video recently posted to YouTube shows the Republican candidate criticizing Kerry in a 2004 speech, saying "this guy really is" a "flip-flopper."

Romney's former support of health care reform in Massachusetts has proved to be a burden on the 2012 campaign trail. Romney has continually argued that Obama's health care legislation was not based on the Massachusetts plan, despite the fact that some of Romney's own health care advisers and experts helped craft the federal health care reform.

This isn't the first time Romney has received criticism for his support of health care reform in Massachusetts. In November, MIT health care economist Jonathan Gruber -- who helped craft the Massachusetts bill -- claimed Romney was "lying" while denying that the bill is similar to Obama's health care reform, saying the two are "the same fucking bill."
