re: Steve Garvey was leading Adam Schiff with 1.8 million votes. What happened?

I think you are confusing the numbers. There were actually two different things people were voting on. One, the remaining term, and the other the term that will begin in 2025. Garvey is leading the race to serve out the remaining term, but is slightly behind in the general election term. Either way, he had a very strong showing this week.
