Despite bearing enormous losses, the Spanish Socialist Workers' Party (PSOE) was able to maintain government, albeit with a mere 1-seat majority.

The People's Party (PP), which in this election made the greatest gains, finished a close second but remained unable to win the PSOE in one of its — considered — strongest strongholds.

Meanwhile, United Left (IU) maintained its presence in the Courts and was able to increase both its vote support and share, but remained unable to gain new seats.

[1] Voting for the Cortes was on the basis of universal suffrage, which comprised all nationals over 18 years of age, registered in Castilla–La Mancha and in full enjoyment of their political rights.

The 47 members of the Cortes of Castilla–La Mancha were elected using the D'Hondt method and a closed list proportional representation, with an electoral threshold of three percent of valid votes—which included blank ballots—being applied in each constituency.
