Why do asian americans support trump heavily?

I'm from Aus but my mum and aunty (Vietnamese immigrant, Minnesota) are very pro-Trump despite literally being immigrants.

I'm in STEM and I struggle to understand why they are anti-vax but wants us to pursue STEM.

I literally have to explain that I could never survive in America because Trump is cutting funding in science.

Why are our aunties trump supporters :(

edit: sorry I can't change the title but yes Vietnamese, please chill about my mistake into lumping my vietnamese family into "asian American" I ain't American so please chill and I'm not aware of what the majority vote

I appreciate those who have provided answers to other ethnicity

thank you for your comments imma read it as it's interesting
