Kamala Harris and Gavin Newsom, both prominent Democrats in California politics for years, may face each other in the 2028 presidential race. Their relationship, marked by public politeness and behind-the-scenes tension, is intensifying as they both consider a White House bid. Harris's recent book included a subtle jab at Newsom, highlighting past communication issues. Newsom has publicly criticized Harris's response to Trump's campaign ads, and some former staff members have transitioned to working for Newsom. The pair's public displays of support belie long-standing personal tensions, dating back to their early careers in San Francisco. Their careers have progressed separately with both rising in politics, yet they have largely avoided competing head-to-head. Both camps maintain a friendly public stance towards each other, but differing strategies indicate a competition. Harris attempts to distance herself from President Biden while Newsom has been using a confrontational strategy against Trump. Former Harris aides are noticing similarities between Newsom's tactics and hers.
