Spanish PM v2

To which party will the next Spanish Prime Minister belong?
People's Party (PP): 40%
Socialist Workers' Party (PSOE): 59%
Some Other Party: 1%

The Spanish election has resulted in a plurality, but not a majority, for the conservative People's Party (see article here, and my earlier prediction here).  A conservative coalition does not seem possible, but a left-wing coalition also seems to be difficult to organize.  I think that a left-wing coalition of some type will eventually be cobbled together.
