Democratic 2020 hopeful Pete Buttigieg is — by every measure — having an ascendant moment as a candidate for president.

Why it matters: The South Bend, Ind. mayor is generating more social media interest on a per article basis than any of his rivals, according to data from social media analytics company Newswhip. And that's just one of many signs of intensifying interest in "Mayor Pete."

By the numbers:

Since his March 10 CNN town hall, he's added 447k followers on Twitter. His next closest 2020 competitor, Beto O'Rourke, has picked up 137k in that period, per CrowdTangle.

Buttigieg has generated more engagement with his tweets (2.10 million interactions) during this period than any other candidate's main account except O'Rourke (2.17 million) — with half as many followers.

During this period, he's added more followers on Instagram (90k) and Facebook (75k) than any other candidate except O'Rourke (92k, 82k), per CrowdTangle.

Interest in Buttigieg, as seen through Google searches, has taken off. As CNN's Harry Enten writes, "Google searches have been correlated with jumps in the polls this primary season."

Buttigieg, 37, has made a name for himself with his unconventional background — he's an openly gay, Episcopalian, Navy veteran, Rhodes scholar millennial who speaks 8 languages.

“If you were to design the exact opposite of Donald Trump, it would be Pete Buttigieg.”

The stories about him that have generated the most interest include:

Linguistic ability: Buttigieg answered a reporter's question in Norwegian. He taught himself the language in order to keep up with an author he liked.

On religion: "We have this totally warped idea of what Christianity should be like when it comes into the public sphere, and it’s mostly about exclusion.”

On MAGA: He said the notion of making America great again is "not honest" because it doesn't address the way the economy is being transformed by automation.

In the last week, Buttigieg has gotten two other pieces of news that point to his rise as a candidate:

He announced Monday that he has raised $7 million since launching his exploratory committee in January.

He polled at 4% in a national Quinnipiac poll. Enten notes that "the move from 1% to 4% is likely statistically significant."

The bottom line: It remains to be seen how much of the Buttigieg interest is a flavor-of-the-month sugar rush vs. momentum that continues to build and can sustain itself for a year and a half.
