Libertarian presidential candidate Gary Johnson is a bad spokesman for marijuana legalization - or so South Carolina Senator Lindsey Graham (R) would have us believe. Yesterday, the senator - who opposes recreational marijuana use - spun Johnson's recent foreign policy gaffe as a win for cannabis prohibition.

Johnson made headlines this week when he revealed that his foreign policy credentials needed some work. During an MSNBC interview, the former New Mexico governor was asked what he thought about Aleppo - the center of the Syrian refugee crisis.

"And what is Aleppo?" Johnson asked in earnest. 

It might be acceptable for the average American to be oblivious to global issues. But an aspiring leader of the free world should probably be more familiar with world news. However, Senator Graham's criticism of Johnson went beyond questioning his credibility as the next commander-in-chief. Graham used the gaffe to take a potshot at marijuana consumers. 

Yesterday, ABC news correspondent Mary Bruce tweeted the senator's response. 

That criticism might be fair if Johnson were high at the time of the interview. He's sworn off cannabis for the duration of the campaign and his term in White House - if he gets elected. So no, we can't blame the gaffe on marijuana. But that hasn't stopped the Twitterati from dissecting the issue. Here are the best comments on Graham's swipe at Johnson. 

Some thought Graham was just having fun with Johnson. 

So maybe cannabis activists were becoming the butt of Graham's joke by taking his comment seriously. But others liked the idea of using marijuana as a cure for American interventionism in Middle Eastern politics.

Of course, cat-gif aficionados weighed in on the issue. 

One commentator added a Canadian spin by taking a swipe at pro-legalization Prime Minister Justin Trudeau.

Others suspected Graham's tweet reeked of hypocrisy.

And one person felt Graham was a poor spokesman for the human race, let alone the American government.
