That's a good idea. Tweeting photos (modified to read "Obama 2014") will get them out to the public and have the fit throwing liberals screaming about them.
That may be the best we can do, but what we ought to do is force them onto ABC, CBS, NBC, CNN and every other "news" organization out there that would refuse to show them if they have a choice.
I've posted one, plus the link on my Pinterest account. Suggest other who have social media sites do the same.
