Bristol Palin's pregnancy is a "damaging revelation " that has caused Sarah Palin's image to "suffer." Says who? Says ABC News, in an article by Rick Klein and Jennifer Parker.

In Palin Pregnancy Rocks Political World, Klein and Parker report reaction from a variety of Republican and traditional-values sources.  Every one, from Dr. James Dobson to Grover Norquist to Chuck Donovan of the Family Research Council to a pro-life delegate to the GOP convention who said "the fact that her daughter's keeping it and marrying the father is wonderful," had a positive reaction.

But what do they know?  Declare Klein and Parker [emphasis added]:

Palin's image may suffer further if more damaging revelations come out in the coming days and weeks.
