But in terms of who you vote for, is that the only moral issue you consider? Do you absolve yourself of pro-active voting on every other moral issue?
This has rarely been more critical than in this election because we are confronted with a candidate whose personal morality can charitably be termed "sociopathic," and whose extreme narcissism determines his every policy. On Howard Stern in the 1990's, he relates how he wanted Marla Maples to abort Tiffany, and while that is the only audio evidence we have on his true "beliefs?" I am sure that it indicates overall callousness towards the preborn.
His only priority is getting reelected and making as much money as he can for his businesses while he is president. At the moment he finds pro-lifers useful. Most are personally conservative. Many seem unconcerned about the immigrant children in cages ("it's their parents' fault") or the protesters killed by Kyle Rittenhouse ("they were violating curfew") or the single moms ("immoral") or the currently unemployed ("they need jobs, not unemployment insurance.") Many are unconcerned about environmental devastation ("4% of climatologists say mankind is not responsible---if climate change is even real.") They are his dream supporters---so undemanding. All he has to do is nominate judges who, while mostly concerned with prioritizing big business over human rights, will secondarily reliably vote against Roe v. Wade.
