"In the mid-20th century, California emerged as a cornerstone of Democratic Party political power. Each decade brought a population boom, and with it, a growing voice in Washington. Between 1950 and 1990, the state gained an average of six new seats in the U.S. House of Representatives per apportionment cycle, largely due to a wave of migration, economic growth and national influence.

But now, that era is ending. According to new projections, the state could lose as many as four seats in the 2030 apportionment — a stunning reversal that would mark the largest single-decade loss in its history."
