Donald Trump's win led to 'rift' in Jennifer Lawrence's family. Find out how

Erecting a barrier along the southwestern border was the defining rallying cry of Trump’s 2016 campaign. “Build the Wall” became a chant, he promised to build 1,000 miles of border wall, and passing on the cost to Mexico was the delicious kicker. Over the past four years, the Trump administration had constructed 371 miles of border barriers, as of Oct 16. And it is on pace to reach 400 miles next week. However, all but 16 miles of the new barriers replace or reinforce existing structures. And Mexico is not paying for it.

With three Supreme Court Justices and 25% of the federal judiciary now made up of Trump appointees, according to data from Russell Wheeler, a judiciary expert at the Brookings Institution, the president has been more successful on this campaign promise than perhaps any other. His nomination of Justice Amy Coney Barrett in the weeks before the election could reshape abortion rights, immigration law and the government’s regulatory power. Confirming a Supreme Court justice so close to an election was unprecedented, and Democrats framed it as an illegitimate power grab by Republicans.

The years long Republican campaign to repeal and replace the Affordable Care Act came to a head unsuccessfully and dramatically in the first year of Trump’s presidency, when Sen. John McCain, R-Ariz., cast the decisive vote against the effort. The Democrats’ regaining a majority in the House of Representatives after the 2018 midterm elections all but doomed any subsequent legislative attempts to strike down the whole law. The president and his party are still trying. Republican lawmakers eliminated the Affordable Care Act’s individual mandate as part of the 2017 tax cuts, and the Trump administration is arguing before the Supreme Court that the whole health care law should go down with it.

The 2017 tax cuts are one of the biggest legislative achievements of Trump’s first term in office, and one celebrated by his supporters. “Business is booming. We’re coming back even stronger after COVID,” said Justin Davies, 36 and small-business owner in Rutherfordton, North Carolina. “The Trump tax cuts have saved us somewhere between $20,000 to $30,000 a year in taxes.” Some critics, however, have noted that the final tax cut that Trump signed into law was far smaller than what he promised as a candidate. The Tax Policy Center, run by the Brookings Institution, estimated that it was only one-quarter the size of the plan Trump campaigned on four years ago.

During the 2016 race, Trump broke with bipartisan orthodoxy and questioned Washington’s decades-long support for free trade deals. He vowed to renegotiate the North American Free Trade Agreement or withdraw from it entirely, pull out of the Trans-Pacific Partnership and raise tariffs. He has delivered on those promises. He withdrew from the TPP in his first days in office. He waged a trade war with China and slapped tariffs on numerous imports, leaving American consumers to bear the financial brunt. He signed the United States-Mexico-Canada Agreement, which included significant changes but also an array of simple updates of the 25-year-old NAFTA.
