In the 2004 elections, out of each 100 electors (Spaniards 18 years and over with a right to vote) 32 voted for the PSOE, 28 voted for the PP, 24 did not vote, 14 voted for other parties, and 2 gave invalid votes or voted blank. Since the 2004 elections till the present, ASEP’s vote estimate for the two major national parties shows a very similar difference to that really observed in those elections, and since the beginning of 2006 the difference has generally been lower than that of 2004, decreasing till a difference of only 1 per cent point in January 2008. It must be underlined, however, that while the vote estimate for the PP is quite stable around 30%, vote estimate for the PSOE shows greater variations that seem to be strongly related with the abstention estimate, so that when it increases vote estimate for the PSOE decreases, and when abstention estimate decreases vote estimate for the PSOE increases. Vote estimate for January 2008 implies that for each 100 electors, 30 would now vote for the PSOE, 29 would vote for the PP, 25 would not vote and the remaining 16 would vote for other parties (including invalid and blank votes).
