She has yet to endorse a 2020 presidential contender, but Rep. Alexandria Ocasio-Cortez (D-N.Y.) has offered her take on a handful of candidacies and worked with several White House hopefuls on legislation.
Why it matters: Since her improbable 2018 win over Rep. Joe Crowley, at the time the No. 4 House Democrat, Ocasio-Cortez has become a household name. The freshman lawmaker has 5.5 million Twitter followers, giving her commentary influence. Her district is 49% Hispanic and heavily Democratic. However, many consider her, as a democratic socialist, the face of the far-left. Just how desirable her favor would be to more moderate candidates is unclear.
