Was the Sabina Matos campaign for US Congress sabotaged ?

There is no need for a prominent ELECTED Democratic politician in Rhode Island like Sabina Matos to cheat on less than challenging nominations papers. As a registered Democrat ( but an INDEPENDENT Democratic Socialist ) I do suspect that Sabina's campaign was , in fact , sabotaged by shadowy opponents. I will probably have a WRITE IN candidate for US Congress in mind on Election Day. Perhaps Arlene Violet ? The evil here is not so much bigotry as crude and amoral political ambition.
