Is this signature presidential?

Ben Carson

Here's how ten would-be presidents and Obama himself make their public mark. This is how they show it was really them that authored a statement and not someone else.  Obama's signature has ballooning shapes, indistinct and large, Trump's is like a fortress and sharply detailed too, Bush is low energy and conventional, Carson is nice-guy-with-zip-and-a-flourish,  Clinton is reserved, stylish, but without flow, Cruz is big-picture with a larger-than-life splash. Walker has so trimmed his public persona it's hard to see what's left.
