'Presidential Selfie' Sisters: See All 19 Pictures With 2016 Presidential Candidates Donald Trump, Hillary Clinton And More

Two teenagers are on a mission to snap a selfie with every presidential candidate. New Hampshire siblings, Addy Nozell, 17, and her 15-year-old sister Emma, have so far snapped selfies with 19 candidates, including Bernie Sanders Sunday.

They only have a few selfies left to take with the 2016 candidates, including Sens. Marco Rubio, R-Fla., and Ted Cruz, R-Texas, along with former Republican Arkansas Gov. Mike Huckabee and former Sen. Jim Webb, D-Va.

Although neither sister is old enough to vote, their Twitter page, named @prezselfiegirls, is grabbing attention.

It all began July 2, when Emma snapped a photo of herself with New Jersey Gov. Chris Christie in Nashua, New Hampshire, where he stopped at an ice cream stand. "We kinda just started with Chris Christie and I just took a selfie and Addy kinda made a challenge to have one with all the candidates. So it's kind of like a fun little summer project we're doing," Emma told CBS News in July.

The girls also caught up with Donald Trump at the Weirs Beach Community Center July 16. "His handlers said, 'These are the girls,' and he said, 'Oh, alright, let's get the selfie,' " Addy told the Associated Press. "We were flabbergasted. Wow. He knew!"

The sisters also attended a town hall in Nashua hosted by Hillary Clinton Tuesday. "It was just amazing," Emma told CNN about the selfie. "We went to the event ... and [as she] shook some hands, my mom and I were freaking out, and we thought we had to get this."

So what do the sisters’ plan on doing once they’ve taken a selfie with every 2016 candidate? They said they'll move on to taking selfies with the vice presidential candidates for their Twitter account, CNN said.

Attending political events is nothing new for them. "Since our parents bring us to all these events, we thought it was pretty do-able," Addy told the Associated Press. "We were always in the parades. We were always making signs. We were always helping them with whatever was needed."

Here’s a recap of all 19 selfies Addy and Emma have taken so far:
