No single reason for the shift in opinions is apparent, but the pattern of changes suggests that the election of a pro-choice Democrat for president may be a contributing factor. Among Republicans, there has been a seven point decline in support for legal abortion and a corresponding six point increase in opposition to abortion. But the change is smaller among Democrats, whose support for legal abortion is down four points with no corresponding increase in pro-life opinion. Indeed, three groups of President Obama’s strongest supporters – African Americans, young people and those unaffiliated with a religion – have not changed their views on abortion at all. At the same time, fully half of conservative Republicans (52%) – the political group most opposed to abortion – say they worry Obama will go too far in supporting abortion rights.
