The decision to step back is yet another sign of the broader drop in morale within the GOP conference. Many Republican lawmakers have largely accepted that their inability to govern is a predicament of their own making. They acknowledge that overcoming their legislative impasse relies on not just keeping control of the House in November, but growing their ranks significantly to neutralize the handful of hard-liners who wield influence by taking advantage of the narrow margins. But many also continue to say privately what few have acknowledged publicly: Republicans believe they are likely to lose the majority.
