Original cartoon can be found here. I updated it to better represent the current political climate.
Update: I realize, at first glance, the character in this cartoon could be interpreted as a couple of individuals. Aaron was a good guess, but note the absence of facial hair on the face and lack of steam coming out of the character’s ears, signifying immense rage.
Update #2: Rachel was yet another good guess. She gets pretty worked up over politics but if I intended for this to be a picture of her I would have made sure she was wearing her awesome tiger shirt.
Update #3: Awesome tiger shirt also pictured here.
Update #4: While my poor artistic skills may have made the stick character look like mom, the dialogue does not match to her. She would be more inclined to say something like, “I don’t like getting in arguments on the internet,” or “I love Clay Aiken.”
