Sabino Matos campaign for US Congress sabotaged ? Cui bono ? To whose advantage ?

With the prestige of an ELECTED high public official in Rhode Island, Congressional candidate Sabina Matos should have had ZERO difficulties gathering enough signatures to get on the ballot. As a longtime independent democratic socialist I find all these Democrat and Republican candidates for US Congress here in Rhode Island colorless . None think outside the box of the national DNC based WOKE WARRIOR ideology. Still I suspect that the Sabina Matos campaign was sabotaged by shadowy opponents in her own RI Democratic Party. To whose advantage ? Cui bono ?
