Sorry mate, I don't know what to tell you. This is how the political cycle works. Announce a big policy and take it to an election so the public can decide whether they want it.
The public won’t disapprove of it by majority.
You don't know that. It's an expensive policy, and plenty of people with private health insurance would feel like their taxes are subsidising the bad decisions of the poors.
