The filing deadline for super PACs came last week and revealed the groups, that operate independently of candidate campaigns has raised hundreds of millions of dollars.

In total, these groups have raised more than $258 million this year. The super PAC backing Jeb Bush led the pack, hauling in a record $102 million. Ted Cruz's super PAC raised nearly $38 million, while those backing Hillary Clinton and Scott Walker took in $20 million.

CBS news writes, "what makes this year so unique is that for the first time, nearly every one of the 22 presidential candidates has their own super PAC, running ads and knocking on doors -- but without the limits on the amount of money any one person can give."

FEC Commissioner Ann Ravel described the Super PAC donation cycle as the "Wild West."  Ravel is head of the FEC that investigates possible violations between PACs and campaigns, like illegal coordination.

"In order for people to have faith in our electoral system, and in the political processes, they have to know that the law is being enforced," Ravel told CBS News. "And people assume it." But she said, it is not guaranteed everyone is following the law. 

According to Ravel it's hard to open investigations. "I think that the likelihood is that the lawyers who are representing all the candidates are saying to them, the commission cannot get four votes to enforce any matter," Ravel said. "Therefore, you can take risks with the law."

CBS reports, "A CBS analysis found that 61 people have given $1 million dollars or more to candidate super PACs. Ravel says the major concern here is that the these mega wealthy donors are buying outsize influence -- and that means less power for the average voter."
