Higher turnout and less active voters turning out. It's nothing to worry about though in my opinion. I say this all the time about 2020 swings to Trump, but with some exceptions (Mahoning County, Miami-Dade, the Rio Grande Valley) most of the swings were probably just temporary noise in a completely unique election. I'm not all that concerned about a 1% or less swing here or in Illinois, Nevada, Washington D.C., etc.
The only California result I am still actively bothered by is CA-25.
Oh wait, a "latinx" discussion? I made a mistake posting here. I will never be back.
I agree it is not cause for concern. The power that LA County had was immense. Frankly, I'm not even that concerned about the LA County swing because LA County also shifted towards Obama in 2012. It seems the incumbent gets a boost.
