The 50th Assembly District falls entirely within the boundaries of Los Angeles County. Richard Bloom (D) is the incumbent in this race. Bloom first won the seat in 2012 when he defeated fellow Democrat Betsy Butler. At the time, Butler was the incumbent.
This district shows the following party registration for the three largest political groups (the source is http://www.l2political.com):
In 2018 we saw Bloom go unopposed for the seat. This is not a shock based on registration being so one sided.
In 2020 we saw Bloom draw two challengers who were both fellow Democrats. Here are the March 2020 results:
Richard Bloom (D)- 78.7%
Will Hess (D)- 14.5%
Jim King (D)- 6.8%
We will now see an inner-party match-up between Richard Bloom (D) and Will Hess (D). Bloom is the elected incumbent and Hess has experience as a documentary filmmaker and paralegal.
Bloom has name ID and resources on his side in this race. I predict that Richard Bloom will win in November.
