As Vice President Kamala Harris parses out the details of her agenda, she has favored broad strokes over detailed policy papers. Only recently has she begun sitting for interviews, which have elicited few details about what her presidential administration might look like.

Little about that careful approach changed during a 25-minute interview with Stephanie Ruhle of MSNBC that was broadcast on Wednesday night. It was Ms. Harris’s first one-on-one interview on cable television since becoming the Democratic nominee.

In her discussion with a friendly interviewer, the vice president again presented herself as a champion of the middle class and hit many of the same themes from her pro-business economic speech earlier in the day. She largely avoided direct questions about how she would govern and why some voters remain fond of former President Donald J. Trump’s stewardship of the economy.

Here are three takeaways from Ms. Harris’s interview.

Harris had roundabout answers to open-ended questions.

Ms. Ruhle’s first question was about how Ms. Harris might respond to people who hear her proposals and say, “These policies aren’t for me.” The MSNBC host’s second was about why voters tend to tell pollsters that Mr. Trump is better equipped to handle the economy.
