TJ Cox (D) officially defeated three-term Rep. David Valadao (R-CA), “giving Democrats a gain of seven House seats in California and 40 nationwide — the party’s strongest midterm showing since the Watergate era in the mid-1970s,” the Los Angeles Timesreports. “Cox clinched his victory more than three weeks after election day, when updated results from Fresno and Kings counties pushed his lead over Valadao to 529 votes. The contest was the country’s last remaining undecided congressional contest.”
