I know Laporta's shortcomings too despite being a big fan, I am not part of the contingent pushing for his return. Although I also recognize that sometimes you have to count on the electability factor to get you over the line too - look at Biden in the US
Otherwise yes you are speaking of Nuñismo which Rosell & Bartomeu are students of, it is indeed the conservative base I have talked about before. They exist much like the Trump kids back across the pond - do they represent the majority? Enough Cruyffists & I would wager enough conservatives still saw Bartomeu's shit show for what it has been to sign the motion, finally.
How that plays out in the coming vote, we'll see. As I say, it's the hope that kills you
