November 7, 2020 - Not a lab accomplishment per se, but as a research lab that studies the diversity, we highlight a few interesting factoids. “To Nate’s point about Democrats and demographics on the ticket, I thought a lot about this during the primary. Since 2000, Dems have had someone from a historically underrepresented group on the ticket — Obama, Clinton, Harris. Joe Lieberman, the 2000 VP nominee, was the first Jewish American to appear on a major party presidential ticket. They won the popular vote each time. The one time they lost the popular vote, in 2004, was when they had two white, Christian men. It’s still not very many observations, but it does suggest that Americans are generally willing to vote for a presidential ticket that doesn’t look or worship like all the ones in the past.” Quoted from: https://fivethirtyeight.com/live-blog/2020-election-results-coverage/ Julia Azari, November 7, 2020, 12:17pm
