Here are the Republican Party's two remaining candidates: DONALD TRUMP

The Republican frontrunner with 64% support, according to Reuters/Ipsos polling, Trump has leveraged his unprecedented legal challenges, which include 91 indictments in four criminal cases, to boost his popularity among his base and raise money. The former president scored victories in nominating contests in Iowa, New Hampshire, Nevada, South Carolina, Michigan, Missouri and Idaho, and is pushing for his allies to take over the leadership of the Republican National Committee ahead of the party's July convention. Trump, 77, has said the criminal charges he faces are part of a political witch hunt designed to keep him from winning, a claim the U.S. Justice Department has denied. Some of his legal challenges have reached the Supreme Court, which ruled that he remains eligible for the ballot following the Jan. 6, 2021 attack on the U.S. Capitol and agreed to weigh his claim of presidential immunity in coming weeks. If elected to another four-year term, Trump has vowed revenge on his political enemies, said he would not be a dictator except "on day one" and pledged to pardon those imprisoned over the Jan. 6 attack. He also wants the power to replace some federal civil service workers with loyalists. He sparked criticism from Western leaders after saying the U.S. would not defend NATO members that failed to spend enough on defense and would encourage Russia to attack them. He pressed congressional Republicans to stall a military aid package for Ukraine. Trump has made immigration his top domestic campaign issue, declaring he would carry out mass deportations, create holding camps and utilize the National Guard. He would also end birthright citizenship and expand a travel ban on people from certain countries. However, his opposition to a bipartisan deal in the Senate that would tighten immigration enforcement has stalled, if not killed, the bill.

He has repeated calls to impose the death penalty on drug dealers, said other alleged criminals could be shot dead, and suggested he would unilaterally send federal troops into Democratic-run localities. On abortion, Trump has taken credit for the U.S. Supreme Court ruling overturning Roe v. Wade, but he has criticized some Republican-led states' six-week abortion bans. He said he supported in vitro fertilization (IVF) treatment access after an Alabama court ruling curtailed access in the state and raised questions about reproductive rights. He has promised other sweeping changes, including eliminating Obamacare health insurance and undoing much of the Biden administration's work to fight climate change.

NIKKI HALEY A former South Carolina governor and Trump's ambassador to the United Nations, Haley, 52, has emphasized her relative youth compared to Biden, 81, and Trump, as well as her background as the daughter of Indian immigrants. She has gained a reputation in the Republican Party as a solid conservative who could credibly tackle issues of gender and race, but she trails Trump in the polls, drawing 19% support among Republicans in the Reuters/Ipsos survey, and has winning one nominating race, in Washington, D.C. Trump has increasingly targeted her, lobbing racist attacks on her ethnicity and amplifying false claims about her eligibility for the White House despite her being born in South Carolina.

Haley, in turn, has sharpened her attacks on Trump, calling him "diminished" and "unhinged" and arguing he is too chaotic and divisive to be effective. Haley has said she would pardon him if he is convicted on federal criminal charges. She has vowed to stay in the race through so-called Super Tuesday on March 5 and has deployed campaign teams to at least eight states voting in presidential nominating contests through March 12. Haley has pitched herself as a stalwart defender of American interests abroad, citing Trump's praise of dictators and slamming his support for Russian President Vladimir Putin after Russian opposition leader Alexei Navalny's death.

She also backs changes to Social Security and Medicare safety net programs for seniors and vowed to dramatically reduce the size of the U.S. government by shifting some federal programs to states. She has said she personally opposes abortion and has sought national consensus on the issue. On IVF, she has said that she believes frozen embryos are babies but that she backs parents' rights over them. Haley has called for making some tax cuts permanent and eliminating the federal gas tax.
