Doom Paul is a series of image macroes that originated on the popular 4chan board /pol/. Doom Paul pictures usually consist of Republican Ron Paul put threw a shitty filter in photoshop with the words "It's happening" or "You could of stopped this".
It's also just about the only meme that /pol/ made.
"OMG THE JOOZ ARE TAKING OVER OMG RON PAUL WILL SAVE US BUT U SHEEP ARE 2 BRAINWASHED TO UNDERSTAND OMG ZIONISM IS EVIL ANTI RACIST IS CODE WORD FOR ANTI WHITE"
