that global warming is both real and man-made." The group found eight members who acknowledged it, although the group acknowledged there could be more and that not all members of Congress have taken a stance on the issue. From 2008 to 2017, the Republican Party went from "debating how to combat human-caused climate change to arguing that it does not exist", according to The New York Times. In January 2015, the Republican-led U.S. Senate voted 98–1 to pass a resolution acknowledging that "climate change is real and is not a hoax"; however, an amendment stating that "human activity significantly contributes to climate change" was supported by only five Republican senators. Health care The party opposes a single-payer health care system, describing it as socialized medicine. The Republican Party has a mixed record of supporting the historically popular Social Security, Medicare and Medicaid programs, and opposing the Affordable Care Act and expansions of Medicaid. Historically, there have been diverse and overlapping views within both the Republican Party and the Democratic Party on the role of government in health care, but the two parties became highly polarized on the topic during 2008–2009 and onwards. Both Republicans and Democrats made various proposals to establish federally funded aged health insurance prior to the bipartisan effort to establish Medicare and Medicaid in 1965.

Neoconservatism, which supports unilateralism and emphasizes the use of force and hawkishness in American foreign policy, has been a prominent strand of foreign policy thinking in all Republican presidential administration since Ronald Reagan's presidency. Some, including paleoconservatives, call for non-interventionism and an America First foreign policy. This faction gained strength starting in 2016 with the rise of Donald Trump. War on terror Since the terrorist attacks on September 11, 2001, many in the party have supported neoconservative policies with regard to the War on Terror, including the War in Afghanistan and the Iraq War. The George W. Bush administration took the position that the Geneva Conventions do not apply to unlawful combatants, while other prominent Republicans, such as Ted
