ABORTION has become the "hot button" issue of the 1990 elections.
In Iowa, the abortion debate has dominated the race for governor and could eventually shape the outcome of a close contest for the US Senate.
In Louisiana, the state senate is expected to vote as early as Monday on the toughest anti-abortion law in the United States. The Louisiana House already approved it overwhelmingly.
In New York, a Roman Catholic cardinal stunned Catholic politicians by indicating they could be excommunicated for pro-choice policies.

New York Republicans made a dramatic reversal in the past month. Their new state platform advocates a clear pro-choice position. It says that government should avoid "regulating people in their personal affairs and lives," and calls for supporting people's "privacy and reproductive rights."
