During the April 2019 Spanish general election, Balbín was elected to the Congress of Deputies for the Madrid constituency. She was re-elected in the general election of November 2019. Politically, she has framed her beliefs as " family, freedom, patriotism." Within Vox, she has served as the party's spokeswoman on gender issues and equality. In this role, she has denounced the Spanish gender violence law and feminism, and has likened positive discrimination(the act of intentionally favoring a racial minority over a racial majority) to Marxism. She has also called on the Spanish government to scrap the gender violence law, arguing "violence has no sex" and claims the law enables false accusations against men. Along with other Vox politicians, she supports abolishing Spain's autonomous communities and calls for the recentralization of the country.
