Would that mean that Delors would have been in 3rd position behind Balladur and Chirac in the 1st round ?!?
No, I really doubt that. I was looking around the 1994 polls on the Ipsos website (on which I have a subscription), and Delors was placing first in most polls for the first round. Of course, Balladur was a strong second then, with Chirac in limbo.
Delors would have been a good candidate for the PS, despite the fact that his pro-market might turn of the lefties in the PS and that he would have been a poor campaigner. Probably better than Jospin even.
