In his first three weeks back in office, President Trump has set a dizzying pace of political and social change, issuing dozens of executive directives meant to dramatically remake the federal government and drive the country in a new direction.

Mr. Trump has continued his pursuit of an America First agenda through selective trade tariffs. At the same time, he has looked beyond American shores in proposing the forced relocations of Palestinians from Gaza to make way for redevelopment. And a fuller picture has emerged of Mr. Trump’s partnership with Elon Musk, a billionaire private citizen, who is barreling ahead with shrinking the government work force.

In some ways, the flurry of striking changes has hardened the fault lines dividing those who strongly support and those who strongly oppose the president. Many more in the middle have adopted a wait-and-see approach.

During Mr. Trump’s first 100 days in office, we will be keeping in touch with a small group of voters — who have diverse political ideologies — to document their impressions of his second term. Here’s what six had to say.
