Despite the glowing words, Mr. Obama abandoned his promise to govern across the aisle, Mr. LaHood said in an interview. The only elected Republican in Mr. Obama’s original cabinet, Mr. LaHood said the president never made a sustained effort to reach out and gave up too easily. As a result, he became isolated and reliant on a group of like-minded advisers.

That assessment from a man who served under Mr. Obama for four years punctuates Mr. LaHood’s new memoir, “Seeking Bipartisanship: My Life in Politics,” published last month by Cambria Press. While he expressed warm feelings toward Mr. Obama and approval of many of his policies, Mr. LaHood lamented the partisan fever that characterized his time in office.

“I do not believe the White House ever committed fully to a genuine bipartisan approach to policy making, despite the president’s words to the contrary,” Mr. LaHood wrote in the book, which he produced with Frank H. Mackaman.

While he said he believed that Mr. Obama was sincere when he said he wanted bipartisanship, the president was hamstrung “by mistakes in judgment and political calculation that prevented cooperation between the political parties and sacrificed vision too easily for short-term gain.”
