Some history: The font in Jeb's logo is a variation of Baskerville, which has been around since 1757. A 2012 New York Times study found that it's the most believable of the fonts -- people were 1.5 percent more likely to find a statement true or agreeable if it were written in Baskerville than five other major typefaces.
Whether in Baskerville or Comic Sans, though, Bush is hardly the only candidate to employ exclamation marks in an attempt to elevate excitement. According to Mark Woods in the Florida Times-Union (which was all over this story years ago), the exclamation mark founds its way to political signs as far back as 1877. Here's a few more notables:
Sen. Lamar Alexander (R-Tenn.) used the ! in his 1996 presidential bid.
The late Sen. Paul Wellstone (D-Minn.) included the ! in his short-lived contemplation of a 2000 bid for president and in his 2002 reelection campaign.
The exclamation point was apparently part of a progression for the progressive senator, who also employed a period.
Rep. Dennis Kucinich (D-Ohio) used the !, too.
So did Rep. John Yarmuth (D-Ky.), who won his 2006 campaign with these signs.
Apparently Sen. Evan Bayh (D-Ind.) was also a fan!
And there's plenty of ! in Bush's home state of Florida, note Florida media. In 2010, the Florida Union-Times reported Democratic state Senate candidate Deborah Gianoulis actually got into a kerfuffle with Republican operatives in the state over her use of the ! and similar coloring and font to Jeb!
Jeb wasn't even the first politician in the state to put the ! to good use, though. That honor belongs to the late former Florida Sen. Paula Hawkins, Abel Harding of the Florida Times-Union pointed out in 2010.
But while the ! is clearly the most popular politician punctuation, it's not the only mark that could say plenty on a campaign.
Just in case all the excitement and responsibilities that come with an ! are a little too much to handle for Jeb! 2016, here's some other ideas we had for the Bush logo.
