The PNC/AFC has become a laughing stock. The PPP "tief" money
The only reason why people might be dismissive of the coalition is that they believe that they might have been involved in some of the PPP corruption.
Maybe the coalition fear that Jagdeo might expose all the little crumbs that he dropped in their laps, when they felt that they would be a permanent opposition, so that they might as well collect their little piece too.
We do know that Jagdeo kept Corbin fed, as when the PNC was threatening to dump him, because they thought that he had capitulated to Jagdeo, he began to bytch and whine and tell the PNC that they had to keep him.
