I think it’s more that pro-smoking plays better with their right wing voter base than taxes. That and the fact that ciggies can still be bought, so the younger generation will still be able to get them. I mean, it being illegal has never stopped any drug. The best way to get rid of smoking is just to ramp up the tax and wait for everyone to take up something cheaper. Even the most hardened smoker at my work now vape instead. Not amazing for you, but got to be better than inhaling all the crap in cigarettes.
Only the mega rich have a solid reason for caring about tax cuts. Everybody else should be clamouring for better services, as that is what will really be cut to give those billionaires more money to hoard.
