George Ishaq Interview

The new Arab Reform Bulletin is out, and includes an interview with Kefaya founder George Ishaq. Noteworthy to me was his statement that the movement isn't that interested in the Presidential elections, and just wants to end the regime. He also stated that their immediate goal was to delegitimize the May 25 referendum. But isn't the referendum tied directly to the elections? Does he just mean they're not interested in supporting candidates for the election, or even noting its passing? And what is Kefaya doing to delegitimize the amendment - I confess I haven't noticed much that ties to it directly.
