Yes, it's really difficult in the times we are living in, with evil all around us. In this situation, we must take steps to avoid the greater evil, such as other politicians who are promoting real, horrible immorality against life and family.
We must prevent these parties or political influences from gaining power. Therefore, I think it could be possible, as a first step, to support or help a candidate who is not so extreme and not promoting anti-life policies. Then, we can work to create influence in politics, social life, and public life to oppose abortion completely.
There was the case where the Roe v. Wade decision was overturned in the United States by the highest court, and it shows that such steps are possible in the future. I hope so.
