Super PACs are unlike traditional PACs in that they may raise unlimited amounts from individuals, corporations, unions, and other groups to spend on, for example, ads overtly advocating for or against political candidates. However, they are not allowed to either coordinate with or contribute directly to candidate campaigns or political parties.
One thing to note is pac money is less efficient than campaign money. Campaigns get the lowest rate for advertisements while pacs pay market rate. Super pacs technically can’t coordinate with campaigns so there isn’t a unified message, however the FEC is pretty toothless so any coordination would likely have to be very blatant for action to be taken. Their advertisements can also be overly biased by their ultra wealthy donors, ie something that musk cares about a lot may not have significant sway on the public which can cause said ad to be wasted.
There are limits to what an individual can donate to a campaign and a PAC. There are no limits to donating to a Super PAC.
