Make the Logo Bigger suggests that it may be time the United States gets a tagline, because maybe it would help our global image.
Obama wants to repair the image of America abroad, and well, why not break the mold and go with a tagline to help win hearts and minds. We’d do the same thing with a new ad campaign, which is essentially what this is, no? Besides, if states can have them, why can’t the country as a whole?
MTLB has gotten some good suggestions in the comments. A few of my favorites:
The Empire You Trust
I can’t believe it’s not democracy
Defending World Champs
Home of the bailouts
Ones I might suggest:
Got democracy?
E Stimulus Unum
It tastes like democracy, but it’s not
Home of the fightin’ feds
But as one commenter suggested, “anything we come up with will get killed in focus groups anyway.” Swap “focus groups” for “committees,” and you have higher ed marketing at its finest.

You would think MTLB would know — you don’t need a slogan! You just need a giant logo! That solves everything.
Heh. Yes, one would think MTLB would know that a ginormous logo is the solution to all marketing and branding issues. Thanks for the reminder.
