This week, the Supreme Court is presiding over what some legal experts are calling a landmark case. The nine justices will determine whether certain sections of the Affordable Care Act are constitutional. Over the last two years, Republicans and Democrats have engaged in a fierce branding war over what to call the law. While the Obama Administration has used the phrases “Affordable Care Act” and “healthcare reform,” opponents of the legislation have labeled it “Obamacare.”

We decided to take a look at the last year’s worth of Google search trends to see which label has gained the most traction. While the phrases “Affordable Care Act” and “healthcare reform” were the most-searched in early 2011, “Obamacare” has become the most common searched term of the three for 2012. We also looked at the top rising searches associated with "Obamacare."
