Two things about polls, you can't always trust them and the devil is in the details. The EKOS poll has been lauded as pure sunshine for the Dion campaign. While you can't dispute the fact that Dion is the clear second choice in the sample, this finding masks other serious problems for Dion:
Delegate Count Based on Probable Attendance(% of respondents likely to attend):
Delegate Count Based On Delegate Retention After First Ballot:
Dion scores lowest regarding his delegates actually showing up to the convention. Dion also scores lowest regarding his delegates remaining with him after the first ballot. Therefore, while Dion may be the preferred second choice, any delegates he could pickup may be countered by bad attendance and lost second ballot support. Interesting to remember, Dion is not likely to pickup considerable second choice support until the third ballot, by which time he may appear so far back that this strategy doesn't pan out.
Momentum will be a powerful force, and the above numbers may well hurt Dion's viability. People will not move en masse to a distant fourth, and in fact it may lead to further internal erosion. While this poll has some good news for Dion, I wouldn't recommend cartwheels, because a close inspection reveals glaring problems beyond the headlines.
