> In reality, virtually every billionaire who has a vocal opinion on abortion is pro-choice, and several have donated hundreds of millions towards the cause.

The first part of this is just false, you're being tremendously selective about which billionaires you're including. There are plenty of stinking rich anti-abortion people who have poured huge amounts into their cause.

Now, as to which group is larger, or richer, I leave that for someone with the time to look at the data, but it is not as open and shut as you're suggesting.
