Why have PAC's increased their monetary donations?

Political Action Committees (PACs) have increased their monetary donations primarily due to the Supreme Court's 2010 Citizens United v. FEC decision, which allowed for unrestricted independent spending by corporations and unions in elections. This ruling has led to the emergence of Super PACs, enabling larger and more coordinated financial contributions to influence political outcomes. Additionally, the growing polarization in American politics has intensified competition for funding, prompting PACs to raise more money to support candidates aligned with their interests. Lastly, advancements in fundraising technology and data analytics have made it easier for PACs to identify and mobilize donors effectively.
