From "binders full of women" to Clint Eastwood and the "invisible Obama," there have been plenty of memes that have gone viral online this election season. Here are some of the best.
Campaigning in Florida in January, then-GOP presidential hopeful Newt Gingrich promised his supporters the moon when he pledged to get the first permanent base on the moon by the end of his first term.
Mitt Romney's white board went viral after he used the prop during a campaign stop in Greer, S.C., in August to diagram the differences between himself and President Barack Obama.
Obama's comments about the relationship between public works and small businesses -- "you didn’t build that, someone else made that happen" -- sent Republicans into a frenzy and generated dozens of memes.
In March, senior Romney advisor Eric Fehrnstrom caught flack after evoking the Etch-A-Sketch to describe how his candidate would adjust to the general election. Not long after, Rick Santorum and fellow GOP candidates used the famous draw-and-erase board as a prop during rallies.
San Antonio Mayor Julian Castro's 3-year-old daughter stole the show during her dad's speech at the Democratic National Convention, tossing her hair back and forth as she watched herself on the jumbotron.
Santorum took style to a new, geeky level with his penchant for the sweater vest -- at one point offering one to supporters who donated more than $100 to his campaign. "Don't let sleeves slow you down," the campaign pitched. "Donate today!"
Rick Perry's "Stronger" ad from last December proved less than popular on the web, where users quickly jumped to produce more unpopular opinions that the Texas governor could use to endear himself to voters, like "The Beatles are a horrible band."
Clint Eastwood made a somewhat bizarre surprise appearance at the Republican National Convention, now infamously addressing Obama by speaking to an empty chair. The Internet went nuts.
Four-year-old Abigael Evans said what many voters were probably thinking recently, when she broke down in tears after listening to yet another report about the election on NPR. "I'm tired of Bronco Bama and Mitt Romney," she sobbed to her mother in a grocery store parking lot.
GOP vice presidential candidate Paul Ryan got the Ryan Gosling treatment when he became the new face of the "Hey Girl" meme, which paired photos of the Hollywood star with made-up quotes.
One of the biggest memes that came out of the 2012 election was Mitt Romney's "binders full of women" comment during the second presidential debate, in reference to the process he used to hire women for cabinet position while Massachusetts governor.
Here's another more memorable spin on the "binders full of women" comment.
There were plenty of memorable moments in Herman Cain's GOP presidential bid, but his time as CEO of Godfather's Pizza is what the Internet really took hold of, although the Pizza Cain Tumblr account has since been taken down.
Big Bird emerged as the unlikely star of the first presidential debate, when Romney said he "likes" Big Bird but might end federal funding for PBS if elected.
In the final presidential debate, Obama scored a zinger when he told Romney the military also uses fewer "horses and bayonets" in response to the GOP candidate's argument about the Navy being smaller now than at any time since 1917.
