That’s not what PPP internal polling data suggests. Somewhere between 57%-60% of Gingrich’s vote would go to Santorum. Romney would have lost both MI and OH if Gingrich withdrew after Santorum’s extraordinary one-day trifecta.
If that’s the case than it steal would help Romney because with that “say” extra 40% of support, it would put him over the top versus a two-man race
