Why take on the 1922 committee?

I don't think I understand why DC had to take on the Tory 1922 Backbench committee. Maybe he suspects that it will cause him massive problems in the coalition or that Graham Brady, the likely new chairman, will make waves. By trying to make the 1922 a meeting of the whole Parliamentary Conservative Party he's made the awkward squad more stubborn and more likely to vote him down on a significant issue.

I don't understand why he is taking on his own party in which sections are still smarting from having their red meat removed from the manifesto menu. The 1922 committee will re-form under a new name and maybe go underground and cause more problems. He may have a much grander plan which he is playing out like chess, but he is playing with Tory fire. It won't be long before they turn...

Squiffy.
