Good point. But sometimes an emerging politician cannot unwind all their deals in time. They bleed over into the election season.
For instance, all the filth that follows EVERY REPUBLICAN EVERYWHERE THEY GO.
Hell, those Republican bastards with their K Street/Goldman Sachs Friends and Family Plans make it darn near impossible to discern when they're doing our Nations' business and when their acting as an agent of their Friends and Family Plan.
Trump doesn't owe anybody any thing.
That's positive and important.
But as a businessman he can act like a child. As a presidential politician he needs to act like a grown up or there’s no way he’ll win. Most people expect more gravitas from a presidential candidate. He could have his lawyers start the lawsuits without spewing about it all over twitter.
