In addition to contributing money to a candidate which is limited to only 5000 which way does a PAC contribute to campaign efforts?

In addition to monetary contributions, a Political Action Committee (PAC) can support campaign efforts through independent expenditures, which include funding for advertisements, mailers, and other promotional activities that advocate for or against a candidate. PACs can also engage in grassroots organizing, mobilizing volunteers, and conducting voter outreach efforts. Furthermore, they can provide strategic advice and resources to help candidates bolster their campaigns. These activities help amplify a candidate's message and increase their chances of success without directly coordinating with the campaign.
