Answer :
Answer: corporation and union spending on elections can be unlimited but not coordinated with election campaigns.
Explanation: In 2010, the Supreme Court ruled that spending towards an election campaign is the same as free speech and for this reason, it is allowed by the First Amendment. This means that corporations and unions can spend an unlimited amount on election campaigns. However, they should not be directly involved with the campaigns. The ruling gave rise to Super PACs that can raise money for a party or a candidate but must not coordinate with the party/candidate.
