Wow. So I was curious to see if that was really his logo, it's that bad. I didn't find out, but I did find this after going to the url jebbushforpresident.com Interesting.
“It’s a piece of shit, and you can quote me on that,” says design critic Steven Heller, who has written dozens of books on everything from branding and typography to infographics and posters.
Actually, the problem is that they are aligned. If you measure carefully, you'll notice that the 'J' the '!' and the "2016" all have their bottoms on exactly the same pixel. The problem is that the heaviest part of the ! and the lightest part of the J both fall at the bottom. It creates an optical illusion that one is not on the same line as the other. That's the mark of a bad eye. Any asshole can have MS Word put two letters on the same line. Even attempting to move them manually (as one would have to do were the case what the quoted person says it is), at least shows that you know how to double click the Photoshop icon on your computer and that you think that Word might not be the optimal program for designing a font for a billion dollar campaign. It is a piece of shit, though. I don't think many would debate the end result, just the why.“The bottom of the curves of the “J” and “!”—the overshoot—almost align. But not quite. It confuses the eye.”
