Bassem Sabry writes, in long piece on NSF travails, that Salafi-NSF made increasingly likely by shared hostility to MB:
Moreover, expanding the common ground with Al-Nour, the largest Salafi party, is a surprisingly possible undertaking at the moment, and the ground is fertile for that matter on nearly everything except the most profound: the amendment of the constitution. The opposition also needs to experiment with new strategies for exercising legitimate political pressure, with the target of bringing Morsi and the Brotherhood as realistically as possible back into a more inclusive democratic process.
