A moment now for presidential campaign slogans.

They can be corny -- "I'm just wild about Harry," Harry Truman, 1948.

They can be awkward -- "Don't swap horses in midstream," Abraham Lincoln, 1864.

They can be brutal -- "Better a third term than a third rater!," Franklin Delano Roosevelt, 1936.

But the best are aspirational, classic and/or memorable -- "A time for greatness," John F. Kennedy, 1960. "Read my lips: No new taxes," George H.W. Bush, 1988.

Unfortunately, the era of summing up a presidential campaign in a romantic sentence is on its way out, says Bill Jasso, a professor of practice at Syracuse University.

As the way we communicate has become more sophisticated, campaign slogans are getting pithier and shorter, Jasso says. (LBJ's "All the way with LBJ" wouldn't fly today, for example.)

He predicts they'll eventually they'll just be a word or two, short enough to fit in a #hashtag on #Twitter with a #link to said candidates' #Web site (#JebCanFixIt, anyone?). Even when they risk backfiring like Jeb Bush's arguably did, hashtags are "simply much more efficient and functional" from a 21st century communications standpoint, Jasso said.

They've also been a part of American politics for 175 years. In their honor, students at Syracuse University's Communications@Syracuse put together this great infographic of history's winning campaign slogans -- complete with 2016 candidates' latest attempts to make it to the slogan history books.

So let's take a moment to remember the weird, the ugly and the great in presidential campaign slogans. We might never have it like this again:
