Soria Ya seems to have taken about half of the left and a third of the right vote. In a general election they could possibly sweep both seats in Soria.
No wonder they elect only 2 members.
Hence "Empty Spain". It had nearly twice that in the mid 20th century.
What sort of people are voting for the Leonese regionalists and for Por Ávila? I note the former got very high shares in some parts of León province, quite widely over 30% in areas around León city and in the north-east, and locally over 40%. El Bierzo doesn't seem very interested in them, on the other hand, and nor do Zamora or Salamanca provinces.
