On the surface, that sounds like good news for John Kerry. But the poll's internal numbers show that 30 percent of pro-life voters will only vote for a candidate who shares their view on abortion. That compares with 11 percent of pro-choicers who would do the same.

That translates into 13 percent of voters who are pro-life and will vote only for a pro-life candidate. They'll be voting for Bush. Only 6 percent of the electorate will be voting strictly pro-choice this year.

The numbers are even more dramatic when viewed in terms of the candidates' overall support. The poll indicates that nearly a quarter of Bush's supporters (23 percent) are single-issue pro-life voters, while only 13 percent of Kerry's supporters are single-issue pro-choicers.

Gallup identified similar trends in both the 2000 and 1984 presidential elections. Likewise, Zogby polling following the 2002 midterm elections indicated that pro-life voters put Republicans over the top in several key Senate races.
