The IFOP poll from April 28 contradicts this: Royal would win. were it not for the +65. by UnEstranAvecVueSurMer on April 29th, 2007. Bush is a symptom, not the disease.
I'd say they're likely to vote relatively more than younger voters.
the exit poll numbers (age group, Royal's %, Sarko's %):
There is now even less doubt that Sarko is the president of the retirees who were most sensitive to his security/anti-immigration propaganda. The IPSOS exit poll numbers ascribing the 24-35 age group to Sarko at 57% didn't make much sense, and the difference with this poll is so large (an 11 point difference) that one can only wonder what happened ...
If I am right that it means the elections were decided primarily by the security/immigration issues, it doesn't say much for the effectiveness of the declinist propaganda.
I note the unwillingness of the media to even mention the age divide in the vote. It seems the left should discuss this point as widely as possible before the legislatives.
One could make that case that on a nice spring day, younger voters are less likely to be at home answering the phone and presumably, an actual exit poll has a much lower margin for error since it gets a better (and larger) sample of actual voters, but simple common sense suggests an error in the IPSOS age cross-tabs.
