Alexandria Ocasio-Cortez explains her stunning upset

Alexandria Ocasio-Cortez, the 28-year-old first-time candidate whose victory over incumbent Rep. Joe Crowley in a New York Democratic congressional primary Tuesday night sent shockwaves through Washington, has a few words of advice for her fellow Democrats: Sharpen your message and avoid petty squabbles with President Donald Trump.
"We have to stick to the message: What are we proposing to the American people? Not 'What are we fighting against?'" Ocasio-Cortez told MSNBC's "Morning Joe" Wednesday. "We understand that we're under an antagonistic administration, but what is the vision that is going to earn and deserve the support of working-class Americans? And we need to be explicit in that vision and legislation, not just 'better,' but what exactly is our plan?"
"I think that's really the path forward... getting into Twitter fights with the president is not exactly I think where we're going to find progress as a nation," she added.
Ocasio-Cortez ran a bare-bones campaign and was outspent by an 18-1 margin. She argued that Crowley had lost touch with his diverse district, both ideologically and demographically, in part due to spending so much time in Washington.
"Our campaign was focused on just a laser-focused message of economic, social and racial dignity for working-class Americans, especially those in Queens and the Bronx. We were very clear about our message, very clear about our priorities and very clear about the fact that even if you've never voted before we are talking to you," she said.
Organization, she said, was also key.
"I started this race out of a paper bag. I had flyers and clipboards and it really was just nonstop knocking on doors and talking to the community," she said.
Crowley, the Queens Democratic party boss who has spent two decades in Congress, was thought to have an inside track to become the next House speaker if Democrats win back the majority in November.
Ocasio-Cortez, however, said that she ran on a message that connected with the people of her district and that's what boosted her campaign and ultimately delivered her a victory.
"I knew that our community needed a very clear voice and I think we deserved representation that rejected lobbyist funds and put our voters and our community first," she said, adding, "I felt like our party could be better, and our message could be better."
Sen. Kamala Harris, D-Calif., said she found Ocasio-Cortez "incredibly impressive."
"I applaud anyone who decides to run for office and put themselves out there because they want to serve the country. I watched her interviews this morning, I think she’s incredibly impressive," Harris said.
