WEST PALM BEACH, Fla. — President Trump has become a virtual homebody during his first few months in office, largely sitting out the honeymoon period that other presidents have used to hit the road and rally support for their priorities.

Mr. Trump, who dislikes spending the night away from home and has been adapting to life at the White House, has rarely ventured far from the Executive Mansion or his Mar-a-Lago retreat in Florida during his first 85 days in office. He has not strayed west of the Mississippi River, appearing at public events in only seven states and eschewing trips overseas. He is planning to travel to Wisconsin on Tuesday, and his first international trip is scheduled for next month, when he is to visit Brussels and Italy for meetings with world leaders.

By contrast, President Barack Obama had made public appearances in nine states and taken three overseas trips by this point in his presidency, and was beginning his fourth journey abroad. And President George W. Bush had stopped in 23 states by mid-April during his first year in office and also visited Canada.

“We are not seeing this president following the norm of going out to the public and making his case in the same way as presidents have for as far back as you want to go,” said James A. McCann, a professor of political science at Purdue University who has studied presidential travel patterns. “Trump is going to his own drummer, as usual. It’s a risky strategy.”
