Bescansa was a co-founder of the political party Podemos, officially registering it as a political party on 11 March 2014 together with Pablo Iglesias Turrión and Juan Carlos Monedero.[1]
In 2014, Bescansa was not on the party list of Podemos, but that year she was elected to the Citizens' Council of the party with about 85% of the votes.[4] This made her the most powerful woman and one of the three most powerful people in the party organization.[5] Bescansa also used her expertise as a political science methodologist in her partisan work, heading the party's political analysis unit and analysing its surveys.[5]
In the 2015 Spanish general election, Bescansa was ranked second on the Podemos party list to the Congress of Deputies for the Madrid constituency, and she won the seat.[6] She launched a candidacy for President of the Congress of Deputies, but lost the race to Patxi López.[7]
In 2017, Bescansa publicly split with the leadership of Podemos, and left her positions within the party.[8] She was subsequently affiliated with a coalition of Más País and Equo.[8]
