A lot of my bullishness on where the Dems are (heading) with Asian Americans (and Vietnamese Americans in particular) comes from seeing how left-leaning and progressive minded Asian pre-health college students, healthcare graduate students, and recent grads in their 20s are as a group- both in real life and online. I will note that there is a gender gap and arguably a class/religiosity one as well.
