Interesting, since earlier polls showed he hadn't taken a hit in Iowa. He's taking one nationally, even amongst Republicans. Reuters:
Allegations that Republican presidential candidate Herman Cain sexually harassed women in the 1990s have begun to damage his bid for the White House, a Reuters/Ipsos poll found.
The poll showed the percentage of Republicans who view Cain favorably dropped 9 percentage points, to 57 percent from 66 percent a week ago.
Among all registered voters, Cain's favorability declined 5 percentage points, to 32 percent from 37 percent.
