Podemos, which contested a general election for the first time after having been founded in January 2014, obtained an unprecedented 21% of the vote and 69 seats together with its regional alliances, the best result ever obtained by a third party in a Spanish election. Coming short by 340,000 votes of securing its campaign goal of becoming the main left-wing party in Spain, it managed to secure second place in 6 out of the 17 autonomous communities and came top in another two—the Basque Country and Catalonia. This result was ahead of what initial pre-campaign and campaign opinion polls had predicted, and was in line with a late-campaign surge in support for the party. Citizens (C's) also had a strong performance for a national party in Spain, but its fourth place, 14% of the share and 40 seats were considered a letdown for party leader Albert Rivera, mainly as a consequence of the high expectations that had been generated around his candidacy. Pre-election opinion polls had placed C's near or above 20% of the vote share, and many also suggested a strong possibility of C's disputing second place to PSOE. Finally, it only came ahead of either PSOE or PP in Madrid and Catalonia. The party also found itself in a weaker political position than predicted, as the "kingmaker" position that was thought to go to C's under opinion polling projections finally went to PSOE, with the Congress' fragmentation resulting from the election meaning that neither the PP–C's nor the PSOE–Podemos–IU blocs would be able to command a majority on their own.
