Politicians from our President's home state would be negatively affected by the his endorsement, according to Public Policy Polling
40% of voters in the state say they'd be less likely to support an Obama endorsed candidate to only 26% who say it would be an asset.
...The numbers on an Obama endorsement are perhaps more relevant with undecided voters. Among those who have not yet made up their minds in the Senate race 21% say an Obama endorsement would resonate positively with them while 33% say it would be a turnoff.
An Obama endorsement does at least go across better with Illinois voters than a Sarah Palin one does.
