Didn't you say you were from Middlesex, bronz?
Anyway, the diversity in Middlesex in interesting because in the 21st century it has gotten very Asian very quickly*. Growing up in the area, a lot of the high schools have become plurality Asian and when you drive down Route 27 from Princeton through the county, it seems like every business has a name with origins from the subcontinent or China. I think it also has the largest Indian-American population by % in the country, and it really shows. Movie theaters sell samosas, there are multiple Indian supermarkets, a neighborhood which is a Little Gujurat, and the town where Trump had his Hindu speech was just outside the county. Definitely more interesting for a suburb than one would expect.
*Now that I think about, it might have the highest Asian % of any county outside of CA and HI other than Queens.
Yes, and Indian-Americans (and even more so other South Asian-Americans) have historically tended to be an extremely strongly (90%-ish) Democratic group, overall, much more so than East Asians. (Though this might have been a little different in 2016, when some Modi-supporting Indian-Americans backed Trump, but unclear how much this was actually a "real" phenomenon among people who otherwise would not have been Republican voters.)
And, yes, Middlesex County has the highest Asian-American population in the US outside of California, Hawaii and Queens and almost certainly the highest South Asian-American population in the US.
Huge Asian-American population + highly educated + not especially wealthy for a NYC suburban county + substantial other minority populations + major state university + overflow from another major university (Princeton isn't in Middlesex County but definitely influences the southern end of the county) makes it obvious it would be a fairly strongly Democratic place.
