I think that would be an own goal for the LP but given they (even post Corbin) so lost on this issue I'm not sure that's a bad thing.
More sunlight and all that....
Truth is Eddie can, as we know, be a highly engaging speaker, but that's using a very different style of engagement, topics and lack of controversy than you would expect from an MP.
When Eddie goes into political mode the absence of Eddie's stage presence, relevance/experience and general charisma is palpable.
