Why is more money geing spent on federal elections that ever before?

More money is being spent on federal elections than ever before due to several factors, including the increasing costs of campaigning, the rise of digital advertising, and the influence of Super PACs and dark money groups that can raise and spend unlimited amounts. Additionally, heightened political polarization has led to more intense competition for seats, prompting candidates and parties to invest heavily in outreach and mobilization efforts. The Supreme Court's Citizens United decision also played a significant role by allowing corporations and unions to spend freely on political campaigns.
