It has been remarked (e.g. at Contentions) that the Republicans, in convention assembled, did not mention abortion overly much. Hardly at all, in fact.
This should not surprise us. John McCain is pro-life; his record testifies to this. Sarah Palin is pro-life; her life testifies to this. And that is the difference between those who do, and those who talk and write.
Deeds, not words, matter most. If you seek pretty words, vote for Obama-Biden. If you seek a pro-life administration, vote for McCain-Palin.
