Without looking at data, I would suggest taxing aluminum first because that will make cheap beer more expensive. Cities will tend towards bars (steel kegs) and independent brewers (glass bottles), while conservatives will drink bud lights from a can.

You could probably do way better with data, and China has more data than any other country. They will find the perfect product to tariff.

Tax whiskey, car parts, and agricultural output ( for example ).

I’m having a hard time finding old articles from Trump’s first presidency but I remember some analysis of the retaliatory tariffs China implemented seemed to target products produced in redder states and counties.

Edit: Finally found what I was looking for (I really dislike mobile versions of websites btw).
