The Sumar Movement, built around Yolanda Díaz, was driven by La Moncloa following the break up of Podemos.
After Díaz's resignation as leader and candidate, Sumar is heading towards self-destruction, with accusations of workplace harassment that have no conclusion.
The internal conflict and the resignation of Lara Hernández, are not due to political disagreements but to a power struggle.
The left in coalition with the PSOE suffers the effects of assimilation and lack of authority and control over its parliamentary group.
The crisis in Sumar exacerbates the agony of the current legislature, at a time without budgets or parliamentary majority.
Conclusion: The internal problems and power struggles in the Sumar Movement reflect a declining politics. The lack of autonomy and a unique profile exacerbates the agony of coalition with the PSOE.
