Spanish Election

Q153: Which party will win the most seats in the Congress of Deputies in the next Spanish General Election?
People's Party (PP): 30%
Socialist Workers' Party (PSOE): 30%
Podemos: 20%
Citizens: 10%
Some Other Party: 10%

The next Spanish election must be held before December 20th, and will likely be held in late October or November (see Wikipedia article here).  Current opinion polls give PP around 25% of the vote, PSOE around 23%, Podemos around 21%, and Citizens around 14%.  There have been a lot of changes in the polls in the past year, however, with significant gains for Podemos and Citizens, at the expense of the two other parties.  I think that the top three parties are about equally likely to win the most seats, while it is rather unlikely that Citizens will win the most seats (especially since they seem to be a somewhat regional Catalan party).
