Over the past 14 months, Twitter users in the U.S. alone have posted some 1 billion tweets about the 2016 election.

And leading up to Tuesday’s election-night results, the most-retweeted comment of the political season so far has been Hillary Clinton’s classic shade-throwing at Donald Trump back in June, according to the social media company.

“Delete your account,” Clinton’s Twitter account posted on June 9, in response to Trump’s tweet saying, “Obama just endorsed Crooked Hillary. He wants four more years of Obama — but nobody else does!” To date, the Hillary riposte has been retweeted more than 532,000 times (and liked more than 694,000 times).

That led to the top retweet for Trump, who has been a prolific and unfiltered Twitter user. “How long did it take your staff of 823 people to think that up — and where are your 33,000 emails that you deleted?” his account tweeted in response to Clinton. As of Nov. 8, that’s been retweeted 169,266 times and liked 298,104 times.

Once the presidential winner is called, however, there may be a new leader among political tweets. The most-retweeted post in Twitter’s history remains Ellen DeGeneres’ selfie from the 2014 Oscars, which has been retweeted 3.3 million times.

Angling to boost traffic on election night, Twitter is the exclusive distribution partner for BuzzFeed’s “Election Night Live” video broadcast. The live-stream is available via election.twitter.com, as well as on the Twitter app for Apple TV, Amazon Fire TV and Xbox One. BuzzFeed also is hosting Twitter’s syndicated video player on its own sites and social accounts.

As far as topics related to the 2016 U.S. election, foreign affairs has been the most-tweeted with 50 million posts since August 2015, followed by terrorism (29 million), the U.S. economy (25 million), gun issues (19 million) and cybersecurity (18 million).

According to Twitter, on Monday 25 million global tweets were sent related to the election from 12 a.m. Eastern through 6 p.m. ET.
