“Weakening” would be more like. Or “exhibiting pusillanimous conduct in the face of the enemy”.
Your goal runs head on into the “quit telling me how to live” streak that’s a strong part of American character.
The “enemy” ends up being voters who don’t share your conviction on abortion but who otherwise vote right of center.
When you tell them that you consider them the enemy and that you intend to use the police power of government against them they believe you. And they won’t vote for you or for your candidate.
The Left understands this. That’s why they always stir the abortion pot. It pits morality police voters against leave me alone voters. For them it’s a winning tactic.
They like nothing better than seeing conservative politicians grab onto that tarbaby. The lure of marching into battle wrapped in glorious virtue is something that they encourage. But America is not a church and its voters aren’t parishioners.
Abortion is the unjustified killing of an innocent human person.
