>>> I do believe the “establishment” is worried about Gov. Rick Perry’s popularity
I note as Bachmann fades her support is switching to Romney. That’s not particularly “establishment”. Perry remains ahead but it’s a competitive race.
If she helps Romney get the nomination, there is probably something in it for her. Romney is paying off Pawlenty's debt. Romney needs Bachmann as much as Bachmann needs Romney. They both are sellouts.
