Trump has privately acknowledged that his decisions, including the war with Iran, may have contributed to the Republican Party's plight ahead of the midterm elections, according to people familiar with his deliberations.
Advisers have become "increasingly blunt" with Trump about poor polling and the party's political challenges.
One person said: "He definitely feels that some of his decisions have led to a dynamic where he's unpopular and things aren't looking great heading into the midterms."
Trump has previously dismissed negative polls as fake, but advisers say he is paying more attention to data showing weak support for him and Republicans.
Trump responded by increasing his focus on the midterms, approving about $140 million in spending from allied super PACs and pledging to campaign in a competitive race. He told advisers he wanted to "fight like hell until Election Day."
