Final answer:
Under President Obama, the Democratic Party favored an expanded role for the federal government, including healthcare reform through Obamacare and initiatives on social issues such as support for same-sex marriage and climate change.
Step-by-step explanation:
Contrasted with the New Democrats, under President Obama the Democratic Party desires an expanded role for the federal government in American life. This expansion is reflected in policies such as the Patient Protection and Affordable Care Act, also known as Obamacare, which aimed to provide all Americans with access to affordable health insurance and to require that everyone in the United States had some form of health insurance. Additionally, President Obama's administration emphasized the support for issues such as same-sex marriage and climate change actions, continuing the legacy of Democratic liberalism that seeks to balance democratically accountable government with government protections and services.
