After releasing their latest statewide numbers for the U.S. Senate and governor races earlier this week, Public Policy Polling notes today that the Democratic candidates here in Illinois are struggling more than most among Obama voters:

Only 50% of Obama supporters are currently committed to voting for Giannoulias and just 48% say they'll cast their votes for Quinn.

No other Democrat we've polled on recently has been getting less than 60% of the Obama vote.
