Who do you mean by we? I don’t know any boomer who isn’t right wing. I know very very few right wingers outside of that generation.
I have boomer family who have voted right wing their whole lives and got more leftist as they got older.
I also know people in their 30s that are out there campaigning for Act, full leopards ate my face stuff.
Generally the people I am close with are not right wing, but that's more a lack of commonalities to base a friendship on. I think you'd be surprised to find how much support National, Act, (and even NZF) get in the younger populations.
