vetoed two bills that would have implemented a single-payer health care system in California in 2006 and 2008, respectively. Schwarzenegger was entrenched in what he considered to be his mandate in cleaning up political gridlock. Building on a catchphrase from the sketch "Hans and Franz" from Saturday Night Live (which partly parodied his bodybuilding career), Schwarzenegger called the Democratic State politicians "girlie men". Schwarzenegger's early victories included repealing an unpopular increase in the vehicle registration fee as well as preventing driver's licenses from being given out to illegal immigrants, but later he began to feel the backlash when powerful state unions began to oppose his various initiatives.

H]e's running back, not even to the center. I would say center-left". Some speculated
