This was an anonymous quote, and doesn't mention "teaching someone a lesson", but is a conditional - the naming of a pro-abortion running mate in 1996, or the inclusion of the putrageoulsy dumb "tolerance plank" in the Republican Platform.
I wouldn't vote for a Republican ticket that included a pro-choice running mate either. Millions of Catholics and evangelicals would as well. So I don't see this as an extreme statement or a threat, rather an accurate interpretation of the conservative Christian vote.
putrageoulsy = outrageously
Look, I invented a new word!
