U.S. Rep. Alexandria Ocasio-Cortez of New York, who just a year ago shook up the Democratic Party by upsetting a longtime incumbent, raked in more than $5 million in donations in 2019, generating buzz about potential U.S. Senate and even White House runs for the progressive 30-year-old congresswoman.

Politico reported Monday that Ocasio-Cortez raised about $2 million in last year’s final quarter and $5.3 million total for the entire year, one of the largest hauls announced by lawmakers thus far.

As a frequent foil to President Donald Trump over social media, a leading fighter alongside Massachusetts Sen. Ed Markey for the Green New Deal environmental legislation, and an enthusiastic supporter and tag team campaigner with presidential candidate Sen. Bernie Sanders of Vermont, Ocasio-Cortez has managed to inspire both increased recognition and financial backing from progressives throughout her first year in Congress.

The $2 million she received in the last three months of 2019 almost reached the $2.1 million in contributions she reported for the entirety of 2018. Ocasio-Cortez’s 2020 campaign has banked more than 325,000 donations from at least 185,000 individual donors, Politico reported. In December alone, Ocasio-Cortez received 120,000 contributions averaging about $16.50.

“Since the first days of this campaign, we’ve known that it will take a movement to challenge a machine. That is exactly what the 185,000 people that donated to this campaign are part of: a movement,” Corbin Trent, spokesman for Ocasio-Cortez, told Politico. “Alexandria continues to prove that if you fight for people, they will fight for you.”

Bucking the Democratic Party establishment, Ocasio-Cortez’s new political action committee raised almost $70,000 in its first day of public fundraising, HuffPost reported.

Ocasio-Cortez, whose upset against 10-term incumbent Joe Crowley gained national attention, launched the Courage to Change PAC to back progressive incumbents and primary challengers like herself.

Fox News recently reported that the congresswoman still wouldn’t pay dues to the Democratic Congressional Campaign Committee along with other members who’ve complained that the DCCC favors moderate incumbents over liberal challengers.

In a tweet, Ocasio-Cortez said, “We are pushing the envelope in DC by rewarding those who reject lobbyist money, fight for working families,& welcome newcomers. Change takes courage.”

“It’s a very exciting launch,” Trent told HuffPost. “When I see so many people stand up and say they are ready to change not just D.C., but the country, it fills me with hope.”
