OK, and suppose that everything you said is exactly as-is and can be proven 100%?
You're looking at a fine, tops, and a paltry one at that.
Cohen broke different laws than Obama's campaign did.
Here is an explanation:
Cohen said that ahead of the 2016 election, he arranged payments to two women to suppress their stories of alleged affairs with Trump. He told a federal judge that he did so in coordination with the then-candidate and in an effort to influence the election.
He admitted to committing two separate crimes that violated federal election law: He caused a corporation to make an unlawful contribution to the Trump campaign and he personally made an excessive contribution to the Trump campaign.
In Obama's case:
Under federal election law, campaigns must file special notices to the FEC of last-minute contributions of $1,000 or more that are received in the final weeks before Election Day.
In April 2012, the FEC released an audit of the campaign that found that the committee did not disclose the identities of the 1,312 donors responsible for nearly $2 million in contributions in the final weeks of the campaign.
Those donations made up one-quarter of 1 percent of the $778 million raised for his White House bid.
The infractions found in the audit were relatively minor considering the volume of contributions, campaign finance experts said at the time.
“Overall, this is a very clean audit report for the Obama campaign. The FEC spent two years picking over $750 million in contributions and expenses and found one violation,” former Republican FEC chairman Michael Toner told Reuters at the time.
Cohen's actions are felonies. They carry federal prison time.
If he committed felonies at the bequest of someone else, that "someone else" is also potentially guilty of a felony.
