This  is interesting:
A new poll of Republican voters finds them not united on the best choice to handle key social issues like abortion. In each of the three first primary battleground states, GOP voters see a different candidate as the best one on the issue.
The Los Angeles Times and Bloomberg News conducted a joint poll of Republican voters in the states and asked them, "Regardless of your choice for president, who do you think would be best on social issues, such as abortion."
Among Iowa voters, the poll found 20 percent thought Mitt Romney was the best to address the abortion issue and Rudy Giuliani came in second at 14 percent. Mike Huckabee and Fred Thompson tied with 10 percent each and others received only single digit support.
In New Hampshire, Giuliani received the support of 25 percent on the abortion question and Romney had 23 percent. No other candidate there received more than 10 percent.
And in South Carolina, Fred Thompson leads on the abortion issue among Republicans with the support of 17 percent to 15 percent for Giuliani and 11 percent for Romney.
In other words, it seems that how Republican primary voters in each state feel about the candidates on the abortion issue roughly correlates with those candidates' standing in that states' polls...which is about what one would expect this early on, when the candidates aren't yet spending big money to "shoot" at each other on specific issues.
