For example, a senator discovered the anomalies of a congressman, he/she can easily cover it up because they are relatives. The other one is, one particular family has power all over the country thus, it results to injustices. In Senator Miriam Defensor-Santiagos Bill, it was observed that political dynasty shouldnt exist in local elective only. While as Sen. Lacsons, not only local the local but also the national position is included. I think both of them have good intentions towards this.
But they need to elaborate more the clause included in the said bill. Many people/government officials doesnt approve of this because it is not clear to them the legal definition of a political dynasty and its corresponding consequences. I also think that it would be unfair for a candidate, who may be more qualified than his family or relative already elected in a public post, to be barred from running because of his relations. It is like we are. All in all, it is good but it should be clearer for the citizens and government to agree upon it.
