Haley has proposed raising the retirement age for people now in their 20s, limiting benefits for the wealthy and using chained CPI, which measures when consumers switch to a less expensive alternative, that would reduce future increases. She has also proposed expanding private Medicare Advantage plans.

Haley supports the 2017 tax cuts.

Haley would bar federal, state and local governments from buying Chinese-made drones; ban the Chinese instant messaging and payment app WeChat and the social media app TikTok; halt exports of technology equipment to China; restrict China from buying U.S. land; and limit scientific and technological cooperation with China. She would consider ending normal trade relations with China over the fentanyl crisis, which has been linked to Mexican criminal groups using precursor chemicals from China.

Haley criticized the Biden administration for using money from the federal deposit insurance fund for customers of Silicon Valley Bank, calling it a “bailout.” She said depositors should have been paid by selling off the bank’s assets.

Haley has called for speeding up permitting of oil pipelines, expanding domestic production of oil and natural gas, and rolling back “wasteful green energy subsidies and regulations” promoting solar panels and electric vehicles, including new emission standards on cars.

At a campaign event in Iowa, Haley gestured away from anti-abortion absolutism — saying that she did not “want unelected judges deciding something this personal.” But her comments were muddled: She said she wanted to leave the issue to the states, but at the same time suggested that she would be open to a federal ban if she thought there was momentum for one. “This is about saving as many babies as we can,” she said, while adding that she did not want to play the “game” of specifying when in pregnancy she believed abortion should be allowed.

Haley has acknowledged that climate change is real and caused by humans, but she has generally rejected governmental efforts to reduce emissions. Her advocacy group Stand for America said that “liberal ideas would cost trillions and destroy our economy.” As ambassador to the United Nations during the Trump administration, Haley was closely involved in withdrawing the United States from the Paris Agreement. At the time, she said, “Just because we pulled out of the Paris accord doesn’t mean we don’t believe in climate protection.” But Haley has supported greater use of carbon capture technology to remove carbon from the air.

When she was governor of South Carolina, Haley signed a law requiring businesses to use a federal database to check prospective employees’ immigration status, mandating that police officers check the status of some people they stopped for unrelated reasons, and making it a crime to “harbor or transport” an immigrant living in the country without legal permission. She has cited this as a national model, though a judge blocked parts of the law, and the state agreed to soften it. Haley has also said that she wants to restore Trump’s “remain in Mexico” policy, add 25,000 Border Patrol and U.S. Immigration and Customs Enforcement agents, withhold funding from “sanctuary cities” that limit cooperation with immigration officials, and immediately deport migrants. But she does not support separating families, she said. She wants to limit birthright citizenship. She told CBS News that she wanted legal immigration to be based on “merit” and businesses’ needs.

Haley says that it is “in the best interest of America” for Ukraine to repel Russia’s invasion, and that she would continue sending equipment and ammunition. In a speech at the American Enterprise Institute, she said Biden had been “far too slow and weak in helping Ukraine.”

Although he supported raising the retirement age and privatizing Social Security in the past, Trump broke with Republicans in his 2016 campaign to say that he would not cut benefits. He urged GOP members of Congress to vote against cuts to Social Security or Medicare in the debate earlier this year over raising the debt ceiling.

Trump signed the 2017 tax cuts into law and frequently cites it on the 2024 campaign trail as one of his signature achievements. He has said that he would extend the expiring tax cuts if elected to a second term. The Congressional Budget Office estimates that extending the tax cuts through 2033 would add $3.5 trillion to the federal deficit.

Trump has called for imposing baseline tariffs against Chinese goods, revoking China’s permanent normal trade relations status, phasing out imports of essential goods from China over four years, barring U.S. companies from investing in China, revoking federal contracts from companies that outsource to China, and banning China from buying U.S. farmland.

Trump signed a 2018 bill that exempted smaller banks from annual stress tests of their assets, which some Democrats say led to the collapse of Silicon Valley Bank and Signature Bank. He has blamed the failures on high interest rates and environmental, social and corporate governance investing, known as ESG. He has also criticized Federal Reserve Chair Jerome Powell, despite appointing him to the position.

Trump has said he would overturn policies under President Joe Biden's administration promoting the domestic production of electric cars. He has also said he would expand domestic oil and gas exploration and production to reduce dependence on foreign oil.

More than perhaps any other Republican, Trump is responsible for the current state of abortion access: He appointed three of the six Supreme Court justices who overturned Roe v. Wade and the district judge who invalidated the approval of mifepristone. He has not said whether he would support a national ban on abortion.

As president, Trump mocked climate science and championed production of the fossil fuels chiefly responsible for warming the planet. He rolled back more than 100 environmental regulations, mostly aimed at reducing planet-warming emissions and protecting clean air and water; appointed Cabinet members who were openly dismissive of the threat of climate change, including Scott Pruitt as head of the Environmental Protection Agency; and withdrew the United States from the Paris Agreement, under which almost every country had committed to try to limit warming to 2 degrees Celsius above preindustrial levels. Trump has given no indication that his approach would be different in a second term.

Trump’s administration separated thousands of migrant families — traumatizing children and causing a public outcry. As recently as May, during a CNN event, he did not rule out reinstating that policy. His administration also forced asylum-seekers to remain in Mexico while awaiting hearings, leading to the development of squalid refugee camps, and held children in crowded, unsanitary facilities. While his signature campaign promise in 2016 was to build a border wall, fewer than 500 miles of barriers were built along the nearly 2,000-mile southern border, largely in places that already had them. One of his first actions upon taking office was to ban travelers from several majority-Muslim countries. In 2019, he began denying permanent residency to immigrants deemed likely to require public assistance, a rule that disproportionately affected people from Latin America, Africa and parts of Asia. Congress did not enact his proposals to slash legal immigration by limiting American citizens’ ability to bring in relatives and by adding education and skill requirements, but he cut it drastically in 2020 through pandemic-related actions.

Trump has said that the war in Ukraine is not of vital importance to the United States. In a CNN town hall event, he did not give a straight answer when asked repeatedly whether he would continue to provide military aid, instead declaring that he would end the war “within 24 hours” by meeting with Presidents Vladimir Putin of Russia and Volodymyr Zelenskyy of Ukraine. Trump — who was impeached in 2019 on allegations he threatened to withhold aid to Ukraine to pressure Zelenskyy to help him electorally — also suggested to Fox News that he could have prevented the war by ceding Ukrainian land to Russia. “I could’ve made a deal to take over something,” he said. “There are certain areas that are Russian-speaking areas, frankly.”
