Upon further research, the meme originates from the web comic goats: the comic strip. I cannot vouch for the funniness of the comic, but I found the bumper sticker on a car at the mall and it made me laugh. Hopefully you also laughed. If you didn’t, you need to lighten up, or educate yourself to the Harry Potter reference.
thats actually kinda funny…it would be really funny if it said “democrats for voldemort”…
just kidding…
