If the poster genuinely supports McMuffin, sure. It seems like there's been a bit of talk that Hillary supporters in Utah should vote McMuffin for strategic reasons, which I find misguided. Hillary needs a majority (i.e., 270) of electoral votes to win.
Winning the most electoral votes is meaningless if it's not a majority. Therefore "denying electoral votes to Trump" has no strategic value.
Now if as the election gets closer the polls start to show a close race between Trump and McMuffin with Clinton well behind and you just want to embarrass Trump then I can understand voting McMuffin though I probably wouldn't do so personally. For now I'd say the proper strategy is to vote for Clinton and hope Trump/McMuffin/Johnson split the Republican vote enough for her to steal those electoral votes. I mean, when was the last time we got to see Utah go blue?
