In aggregate, you will find that the population of Silicon Valley, and wealthy locations in general, under-enlist, tend to vote against military appropriations, and if they do vote for increased military appropriations, they tend to vote for larger non-lethal military capabilities (e.g. they favor military healthcare and retirement benefits). A lot of this is obvious blue-state voting. For the enlistment rate, the easiest one to point to is Texas vs California. Texas accounts for 12.1% of Army recruitment from a population of 29M, while California accounts for 9.9% of Army recruitment from a population of 39M. New York is even lower with 4.6% from a population of 19M. By comparison, North Carolina has 4.7% population on a population of 10.5M.
