Before Obamacare was Obamacare, it was Romneycare.
Before Romney was against Obamacare, he was for Romneycare.
Romney lacks a political soul - he's a political opportunist. He'll jump aboard anything he thinks will help his standing with whichever constintuency he's trying to pander to.
Romney created Romneycare in Massachusetts because he hoped to use it as a talking point for his 2012 Presidential campaign to sway Independents, Moderates, and Liberals.
Romney is a walking major fail. He wore out his welcome in Massachusetts. He'll wear out his welcome in Utah. He can't slither to Michigan because that state's GOP doesn't want him.
