One of the great things about David Barton is that once he has adopted a talking point, he continues to repeat it regardless of how absurd or out of date it has become.
For example, earlier this week Barton appeared on "Praise the Lord" where he told hosts Matt and Laurie Crouch that legal abortion will not be an issue in twenty years because God has sent a new generation of teenagers who are overwhelmingly pro-life.
Claiming that polls show that 72% of teens oppose abortion, Barton said they were "an answer that God has sent with a new generation; we just gotta train these guys right and turn them loose to get this thing fixed":
If you actually bother to find the poll Barton cites, you discover that it is from 2003 and it found that 72% of teens thought that abortion was morally wrong.
If you trust Barton, then abortion should be illegal within the next decade, since the poll he is using it over ten years old. The only problem is that the teens in that survey are now adults and according to a Gallup poll conducted in May of this year, 50% of adults ages 18-29 consider themselves to be pro-choice while 41% consider themselves to be pro-life.
Of course, as with so many of Barton's other talking points, he doesn't bother to mention any of that because doing so would completely undermine the very claim that he is making.
