SAN DIEGO — Sen. Dianne Feinstein, who has served in Congress since 1992, didn't receive the California Democratic Party endorsement this weekend. Neither did her progressive challenger, Kevin de León, but he earned nearly 20 percentage points more among the delegates' votes.
Why it matters: Grassroots progressives want to push the party farther to the left, and voters are listening. Democrats aren't just fighting against President Trump — they're fighting each other and struggling to agree on the party's identity. All of those tensions were on display at the California Democratic Party convention.
