A new survey shows that Republicans are much more unified in their views on abortion than Democrats.

The Gallup survey shows that 2/3rds of Republicans call themselves "pro-life" no matter what their age, income or education level.  On the other hand, Democrats are much less homogenous when it comes to being "pro-choice."  

According to the pollster's analysis, that could play a factor in Mitt Romney's quest for the GOP nomination.

Such unity would normally suggest that the Republican nomination will be decided on something other than abortion. That would seem particularly true this year with the economy and federal budget deficiteclipsing other concerns in voters' minds. However, Romney's candidacy could change that if his competitors decide to make his past positions in support of abortion rights an issue. The Gallup analysis of Republicans' abortion views suggests that such criticism of Romney could be broadly communicated to GOP voters in a way that might not work for abortion messaging in the Democratic Party. It would matter little if Romney's GOP opponents make their case at a $1,000-a-plate dinner in Ohio, a down-home picnic in New Hampshire, or to college Republicans -- the audience would likely be sympathetic to a pro-life message. Whether Republicans would care enough to prioritize questions about Romney's sincerity on abortion over other issues remains a different matter.
