What primary concern do political observers have on the role of political action committees?

Political observers are primarily concerned that political action committees (PACs) can disproportionately influence elections and policymaking due to their capacity to raise and spend large sums of money. This financial power can lead to a lack of transparency and accountability, as PACs may prioritize the interests of their donors over the broader public good. Additionally, there are fears that PACs can exacerbate political polarization by favoring extreme candidates or agendas, undermining democratic processes and public trust.
