They should bring it up now with an ad. Start it with, “Obama is distorting his record on PBA/protecting life...but here’s the truth...” (I wouldn’t yet use the word infanticide, though that is what it is.)
“Obama is distorting his record on Abortion, but here’s the truth...”
Abortion is the word I would use. And then describe what can only be viewed as infanticide. It will do us good because it then connects “abortion” to what is even (if possible) more hideous, infanticide, without ever having to use the word.
