No, it doesn't change it across the nation. A fetus is still not a person, the law simply states it is a more heinous crime to harm a pregnant woman.
Funny, but the YUnborn Victims of Violence act defines an unborn CHILD as follows:
"d) As used in this section, the term 'unborn child' means a child in utero, and the term 'child in utero' or 'child, who is in utero' means a member of the species homo sapiens, at any stage of development, who is carried in the womb."
If it is a CHILD, it is therefore a PERSON at any and all stages of development. The act also allows for those who murder a pregnant woman to be charged with two counts of murder, one for each PERSON they killed.
