Some Q's ...
Given that the stories are that Tump has paid off several women over the years for affairs, how can they prove that his latest payoff was specifically for the campaign in order to classify as an illegal contribution? The former head of the Federal Election Committee has said that these payments could not constitute a campaign contribution.
While we're talking about payments for a campaign ... did Clinton disclose the $9 million payments made through her campaign law firm to Fusion GPS and the Russian agents to create the dossier on Trump specifically for the purpose of her campaign? Has she been investigated for this and if not, why not? Is this illegal campaign contribution and Russian collusion? If not, why not?
Does the fact that Manafort and Cohn judgements were made on the same day strike anyone as suspicious or is it just a big coincidence? Same with the press making demands to have the names and addresses of jurors before they deliberate - couldn't that be considered a form of intimidation? Because being doxxed could well result in a violent Antifa mob if they didn't return what they considered the 'correct' result.
Who remembers Barrack Obama's campaign receiving one of the largest fines ever for $millions of illegal campaign donations / hiding donors by the Federal Election Committee? Was he indicted for it and stripped of the president?
I predict that most Trump supporters will find ways to rationalize away his illegal behavior rather than admit they were wrong.
First of all, you have to prove something illegal has happened. Second, you have to look at the typical handling of such incidents - impeachment would be dramatically excessive given previous cases.
You seem to be the one trying to 'rationalize' that everything that happens should = impeachment! This is the Trump Derangement Syndrome that many now seem to be afflicted with. I think many believe that it's a crime for the president not to be the one they voted for. Sorry, that isn't how elections work and if you think the election wasn't fair you have to prove it and none of what is happening is anywhere near to doing that. Mueller just got to trawl on a fishing expedition backed by the FBI and turned up some fish.
