Who are the BLUES and who are the WHITES?
I’m not too up on Israeli politics but Blue and White are I think a left wing political coalition - named for the colors of the Israeli flag.

Sorry I said left wing, but I think it is a combination of left/right. Wikepedia says “center/center right” but I’m not sure that is accurate either. One of the parties in the coalition was in the previous Netanyahu government. Maybe someone else can color in the affiliations.
