“We agree entirely with Gov. Romney and Mass. legislators that our goal should be 100% insurance coverage...”

That's from a memo penned by Newt Gingrich in 2006.

As Jonathan Karl points out:

And, Gingrich wrote, the key to achieving that goal was doing what Romney did in Massachusetts: Requiring everybody who could afford it to buy health insurance. In fact, Gingrich makes an impassioned case for the so-called individual mandate — which is also at the center of President Obama’s health plan — on conservative grounds.

“We also believe strongly that personal responsibility is vital to creating a 21st Century Intelligent Health System,” Gingrich wrote in the memo which was found on an old Gingrich website by BuzzFeed’s Andrew Kaczynski. ”Individuals who can afford to purchase health insurance and simply choose not to place an unnecessary burden on a system that is on the verge of collapse; these free-riders undermine the entire health system by placing the onus of responsibility on taxpayers.”

I imagine Romney will rightly use this to shrug off modern criticisms from Gingrich on his way to securing the nomination in 2012.
