I like Moshe a lot, but I think he's making a mistake in thinking he can take over the Likud. I think the latest fiasco with Bibi unilaterally postponing the central committee elections was proof positive that the LIkud will break the law to prevent a rightwing takeover from Feiglin.
When they were debating whether to continue their current strategy or to bolt from likud and form an underground party or strategy, I thought they should abandon the likud strategy, but they stuck with it. I'm not sure if they stuck with it because they really think that is the most effective way, or if, in light of recent events they don't even believe in it anymore, but there is a lack of infrastructure in place on the ground for them to yet form a breakaway movement.
