Having recently finished reading the book Donald Trump doesn't want you to read, I've concluded that, as far as politicians go, Trump isn't that bad. Yes, he's vain, arrogant, greedy, narcissistic, and a bit delusional, but so are most of his competitors. At least he's up front about it. He's not hiding behind a carefully managed facade. With Trump, what you see is what you get. His skeletons are already out of the closet.
In fact, I believe that Trump, if elected, will be the least corrupt president since Eisenhower. I don't know much about Ike, but from my reading I've learned that each of his successors* has been involved in all sorts of really shady stuff. Stuff that makes Trump look like a boy scout.
Trump's no saint. If elected, he will become the latest in a long line of corrupt executives, but let's not lose perspective. He will only be the most corrupt president since the last one.
*with the possible exception of Jimmy Carter
