They're getting into a pissing match precisely because there is negligible policy/voting record differences between them
and aren't friends.
There are still two San Fernando Valley districts with but negligible territory removed - and one of them is now very very clearly drawn as a Hispanic opportunity district (which could have been done ten years ago - when it would have been weaker, the Hispanic bench in the area would have been much weaker, and Berman probably could have held it in a primary). There really wasn't anywhere else to run.
