Presently, individual donors can contribute $123,200 total to candidates, national party committees and certain political committees. No one donor can give more than an aggregate $48,000 to individual candidates.

If the cap was removed, someone potentially could donate an aggregate of millions spread between various candidates.

McCutcheon reportedly donated thousands of dollars in the last election cycle and said he would have donated more if not for the spending caps.

In the initial Supreme Court filing submitted in October 2012, records indicated McCutcheon “wanted to express his support for, and associate with, candidates as permitted by the base limits without a biennial limit.”

The Republican National Committee joined McCutcheon in challenging the current cap. They contend the restriction is a violation of the First Amendment and free speech.

Several Michigan organizations, including consumer advocacy organization PIRGIM, the Michigan Campaign Finance Network, Common Cause Michigan and Communications Workers of America said the current cap is in place for a reason.

“The cap on aggregate contributions is $123,000 per election cycle, which is well over the average total income of most Americans,” said Eric Mosher, program associate with PIRGIM.

Since the 2010 Citizens United ruling, which determined that restricting contributions from corporations, associations or labor unions is unconstitutional, “politicians have even less of an incentive to listen to constituents,” Mosher said.

Some advocates argue that this is moving the country toward a climate of political corruption.

Rich Robinson, executive director of the Michigan Campaign Finance Network, said repealing those limits would bring the federal government on-par with Michigan campaign finance law, which he believes is not a good thing.

“There is so much in Michigan state campaigns that is not disclosed that it’s hard to tell what the biggest contributions are doing,” Robinson said.

Advocates say they fear politicians will have even less of an incentive to rule by the wishes of the majority if these limits are removed.

A new report from Demos, a public policy organization that advocates for stricter limitations on campaign contributions, suggested that might be too far-fetched.

In 2012, 1,219 donors gave a collective $155.2 million to candidates, parties and Political Action Committees throughout the nation, according the Demos report.

Without current limitations, the report estimated those donors would have given $459.3 million in the last election cycle — more than 47 percent of all funds raised by President Obama and presidential candidate Mitt Romney from at least 4,040,442 small donors.
