When the British political strategist Deborah Mattinson heard Vice President Kamala Harris boast in the presidential debate about prosecuting transnational gangs, she thought the message was spot on — and that Harris needed to deliver it many, many, many more times.
The former head of strategy for Prime Minister Keir Starmer, who won a landslide election in July, Mattinson was in Washington the week of the debate to meet with Democrats, including advisers to the Harris campaign, and share lessons from the Labor Party’s smashing summer victory. She and Claire Ainsley, Starmer’s former head of policy, urged Democrats to focus intently on winning back working-class voters who had drifted to the right in recent years — toward right-wing populists who seemed more in touch with their economic frustrations and cultural grievances.
“For voters, cost of living and immigration are the two biggest issues,” Ainsley said. “And that’s where they need to focus their attention.”
POLITICO spoke with Mattinson and Ainsley as they were wrapping up their visit to Washington. Harris, they said, was on the right track. But with only weeks left until the election, there was still plenty of work for her to do to defeat former President Donald Trump.
Their advice was not just based on intuition or interpretation of the recent U.K. election. Ainsley is a leader of the Progressive Policy Institute, where she directs a transnational effort to revitalize center-left parties. As part of that effort, the think tank shuttled Labour politicians to Washington earlier this year and the Democratic convention in August, and conducted polling and focus groups in American swing states over the summer.
