Given the mandate that voters bestowed on Islamist parties in parliamentary elections a year ago, however, it’s hard to imagine that a constitutional draft would read the way non- Islamist groups would write it. The document can be amended by a Parliament to be elected once a constitution is in place. To exploit that possibility, the opposition should be able to point to a significant “no” vote in the referendum, as a sign Egyptians want changes. Non- Islamists also need to do well in the parliamentary balloting. Accordingly, opponents would be wise to ditch their tactics of disruption and seriously contest the referendum. They can continue to call for Mursi to rescind his extraordinary powers while also carrying out a funded, staffed, coordinated campaign to get out the “no” vote.
