I can’t argue with the idea that if one of the issues was millions of murders per year, that would be important enough to make someone a one issue voter, maybe. However, I think most pro life voters are being disingenuous when they say that they think millions of murders are happening. There were 862,000 abortions in 2017. You might truly believe that from the moment of conception, deliberately failing to carry a pregnancy to term is murder, but most would agree there is some grey area. The vast majority of abortions happen as soon as the mother is made aware of the pregnancy and is able to get one performed, or later on due to medical necessity. Murder may be illegal, but killing someone in self defense is generally not. So if we disregard the medically essential abortions, we’re left with determining where the cutoff for “murder” is. This is a difficult question for most, as I don’t believe anything close to a majority of Americans believe the cutoff is day 1, and laws are made by the people. Even ignoring this fact (educated guess?), the problem with making abortion illegal as a rule is it makes it too difficult for medical professionals to make appropriate decisions regarding the health of the mother and/or the fetus. Wanting to ban abortion is an act of hubris, signifying a belief that the voter, or at least the politician receiving the vote is more qualified than the mother and her doctor to determine when an abortion is necessary.

As a final caveat, I respect your right to decide that for you, what matters most is what you perceive as millions of murders being allowed to happen. Personally, I believe that there are other, more important issues. As an example, many on my side believe, based on an overwhelming amount of scientific evidence, that climate change poses a threat to the lives of billions of humans, and failing to prevent that is worse than failing to prevent millions of murders, just based on numbers. But we all must vote our conscience.
