Obamacare/Affordable Care Act: This is comprehensive health care reform legislation passed under President Obama that aimed at making health insurance more affordable and accessible. Like offering discounted gym memberships to encourage more students to exercise.
Birther Movement: A political movement that falsely claimed President Obama was not born in the United States, and therefore ineligible for presidency. It's like a school rumor questioning the qualifications of a popular student running for class president.
Stimulus Package: An economic policy aimed at boosting the economy during a downturn. Under Obama, this included the American Recovery and Reinvestment Act of 2009. Think of it as extra funding given to clubs and activities when student participation is low to boost involvement.
