Dem poll shows Mourdock tanking, Donnelly up 9 in Indiana

Democratic Rep. Joe Donnelly has established a clear lead over Republican Richard Mourdock in the Indiana Senate race, according to a poll taken for Donnelly’s campaign in the wake of Mourdock’s damaging comments about abortion and rape.

In a Global Strategy Group poll shared with POLITICO, Donnelly now leads Mourdock by 9 points in a two-way race, 47 percent to 38 percent. When a third candidate, Libertarian Andrew Horning, is added to the poll, Donnelly leads by 7 points — 43 percent to 36 percent to Horning’s 9 percent.

Mourdock’s personal image has taken a beating, with his unfavorable rating rising 9 points in the past 10 days to 49 percent. Among undecided voters in the Donnelly poll, only 8 percent have a favorable view of Mourdock while 46 percent view him unfavorably.

There has been little available polling on the Indiana Senate race since Mourdock’s problematic debate performance, but private polling on both sides has shown real bleeding for the GOP state treasurer.

The GSG poll was taken from Oct. 28-30, surveying 600 likely voters with a margin of error of plus or minus 4 percentage points. You can read the full polling memo here.
