This is already an old article, but it is worth looking at for Americans interested in the respective prospects for their two major parties: "The Empty Cradle Will Rock: How abortion is costing the Democrats voters--literally." The subtitle pretty much gives away the thesis of the author, Larry L. Eastland. Others have picked up on the phenomenon Eastland has identified, but he brings out some fairly precise numbers. The author's conclusion?
Abortion has caused missing Democrats--and missing liberals. For advocates so fundamentally committed to changing the face of conservative America, liberals have been remarkably blind to the fact that every day the abortions they advocate dramatically decrease their power to do so. Imagine the number of followers that their abortion policies eliminate who, over the next several decades, would have emerged as the new liberal thinkers, voters, adherents, fund-raisers and workers for their cause.
If Eastland is correct, then the Republicans look set to run the United States for the foreseeable future, unless the Democrats change their attitudes. Perhaps they might turn to Democrats for Life for help in reversing their fortunes.
