There’s always been a mix of politics and business, and some of that does turn into illegalities. If Trump had illegal dealings with any politician, I’m sure it would have come out by now. Merely donating to a politicians campaign is not illegal, but if you can prove that the politician was actually receiving bribes, that’s illegal. So, if you think that Trump’s deals were illegal, you are more than welcome to invest a lot of time examining all of his dealings. I would think that Cruz, Rubio, Bush, Clinton, etc., have probably had their Opposition Research crews working on this very subject for many months. We’ll have to wait and see, but by all means, start your own investigation if you want.
Why would the left or the media, but I repeat myself, bring out anything negative about Trump now? If you've been paying attention virtually none of the MSM has said anything negative about Trump's business dealings this election cycle. They want him as the candidate to run against Hillary.
As soon as he gets the nomination the onslaught of Trump's dirty laundry will begin. Do you thing people like Cruz can penetrate a business empire like Trump's? The vast number of Trump's dealings are with other lefties. They are the ones that hold the dirt and can let it flow when the time is right.
And I don't have to “prove” Trump bought politicians for political favors, he says as much. He's proud of owning them. It is all about power and who's in charge - just ask him.
