3 of those presidents are not like the other. They had grace and dignity, two qualities which are completely absent in Trump. You've overlooked the whole point that he is actively undermining the legitimacy of his own office to point out that he wasn't a war hawk. It's definitely a plus that he didn't start any new wars. But he's still a giant piece of shit.
I'd rather have a piece of shit that doesn't start wars instead of having two faced fucks that are politically correct but dead inside.
Trump is a saint compared to Obama.
