It is almost always sinful to vote for Democratic candidates despite what the mainstream media tells you. For example, this is fundamentally dangerous: “I’m pro-life and I voted for Beto O’Rourke because I’m done being used by the GOP,” declared one opinion piece in the Dallas Morning News. One does not solve evil by resorting to a greater evil. The moral decision here is that I don’t want to see babies murdered, so I’m going to vote for the Democratic Party and more murdered babies. That is stupid. That is sinful.
If someone claims the GOP is using pro-life voters, then the only responsible reply would be not to vote for the GOP.
