Kansas billionaire Charles Koch now says that he regrets his partisan spending—admitting in his new book that it only made things worse, according to The Wall Street Journal. The 85-year-old tycoon’s book, Believe in People: Bottom-Up Solutions for a Top-Down World, says that he is shifting his focus from intense Republican partisanship to finding unifying answers to social issues instead. “Boy, did we screw up!” Koch writes. “What a mess!” He now wants to work together with Democrats and liberals like the American Civil Liberties Union, the LeBron James Family Foundation, and Democratic state legislative campaigns. “I congratulate Joe Biden and Kamala Harris on their victory,” he said in an email to the Journal. “I look forward to finding ways to work with them to break down the barriers holding people back, whether in the economy, criminal justice, immigration, the Covid-19 pandemic, or anywhere else. At the same time, I hope we all use this post-election period to find a better way forward. Because of partisanship, we’ve come to expect too much of politics and too little of ourselves and one another.”
