To the surprise of only those who have never heard of California's 17th Congressional District, eight-term incumbent Democrat Mike Honda and fellow Democrat/fellow progressive Ro Khanna wound up in a dead heat in a renewal of their 2014 electoral battle.
Secretary of State's vote returns showed Khanna with 38.3 percent and Honda 38.1 percent with 100 percent of precincts counted.
With two Republicans, Peter Kuo and Ron Cohen, trailing far behind, California's top-two primary system triggers an all-Democratic race in the 17th District general election.
Two years ago, Honda won a narrow general election victory in a district that encompasses slices of southwestern Alameda County and eastern/northern Santa Clara County. Honda won the June 2014 primary over Khanna by 20 percentage points, then squeaked by his challenger in November, 51.8 percent to 48.2 percent.
