What Am I Missing Here?
There has to be some reason that 11 members of the Idaho House voted against this bill. Maybe because they don't believe in a woman's right to choose? From the March 25, 2008 Idaho Statesman:

BOISE, Idaho — The House has passed a measure making it a crime to violently coerce a woman into getting an abortion.

Lawmakers voted 55-11 on Tuesday to approve the bill, a scaled-back version of an earlier proposal. The bill now goes to the Senate.

The measure would apply to anyone who threatens, conspires or inflicts physical injury or death on a pregnant woman.

The crime would either be a misdemeanor or a felony depending on whether the offense involves actual violence.

Republican Representative Bob Nonini of Coeur d'Alene says the bill would help protect pregnant women who are pushed to do something they don't want to do.

Oh, here's the explanation:

Opponents say the law is unnecessary since the threat of physical violence is already a crime.

And so having a second statute under which someone can be charged is a problem because....what? I would think that there are a number of situations where a person could be charged with different crimes for what is essentially the same offense.
