FiveThirtyEight founder Nate Silver claimed that racism and sexism are why 29-year-old Congresswoman Alexandria Ocasio-Cortez drives “certain Republicans crazy.”

“There are lots of reasons Ocasio-Cortez drives certain Republicans crazy,” Silver tweeted Tuesday, “foremost among them her race and gender.” Additionally, he asserted that criticism also stems from the fact that Ocasio-Cortez is “quintessentially a New Yorker and DC political culture is formal and prudish when NYC mostly isn’t those things.”

“Put differently, New Yorkers are very good at trolling, and Washington has extreme troll-vulnerability,” Silver added. “It’s always made for a mismatch but more pronounced now that we’re in the Golden Age of Trolling. We may need to move the capital back to Philly to keep it a fair fight.”
