The tax question is not a surprise though. There are many ways other than tax rates for a govt to raise revenue. Millennials are saavy and know this.
But if you narrow it down to an EXCLUSIVE option, that changes things.
I would not call that a flip.
I would say that 13% found tax as the only revenue generation changed their stance.
I’ll give an example:
a) Legalize pot and tax it. You’ll get broad support.
b) Increase existing tax. You’ll get less support.
