Yes I know I need to upgrade.

Well trying the above I get:

test=> select
     sum(vote.total), st
from
     public.vote,
     public.state
where
     vote.city = state.city
group by st
order by
     sum(vote.total) desc;

  sum | st
-----+----
   85 | ca
   11 | ny
(2 rows)

To get the column order you show I did:

test=>select st, sum(vote.total)
from
     public.vote,
     public.state
where
     vote.city = state.city
group by st
order by
     sum(vote.total) desc;


  st | sum
----+-----
  ca |  85
  ny |  11
(2 rows)


So I am not sure what is not working on your end?
